For the fun the of it, I decided to start a thread on rating the difficultly of written song parodies.

The scoring system is 1-5, with 1 being very easy and 5 being very hard. You can also describe why you chose a paticular song and ratings with decimals can be used(example 3.5).

I start it off. I've done more than one parody to the same songs ,so I'll go by original song.

Sliver: This is the first song I've made a parody of. One of my favorite songs.

Parodies:
Training Trip: Difficulty 3
Three$ome at Excel's home: Difficulty 3.5

About a girl: I've done two parodies of this one now.

Parodies:
Kill Happosai: Difficulty 2.5
Please Twins! Trilogy: About Them: difficulty 2.5

Jesus wants me for a sunbeam: Dragon ball Z for some reason came to mind.

Parodies:
Frieza doesn't want me in the ginyu: Difficulty 2

Sappy: One of my most favorite Nirvana songs, the earliest form of this parody was written in early 2002. I wrote a better version of it a couple of months ago.

Parodies:
Sappy(Maison Ikkoku version): Difficulty 3.5

Mexican Seafood: A fun, but short song I like. Wrote two parodies for it, kinda tricky to do. The pacing of this Nirvana song is quirky.

Parodies:
Anime F***ing Perversion: Difficulty 1.5
Pokemon Grunge Song: Difficult 3

Oh the Guilt: A song that is on the boxset and the Nirvana/Jesus Lizard single. I've done two parodies of this song, both were wrote using a live version.

Parodies:
Oh the Guilt(Nanako version): Difficulty 2
Digicharat crew: Difficulty 3

Verse Chorus Verse: refered to as "In his hands" on bootlegs. A version of the song is also on the boxset. The only song I did two different versions of the same theme.

Parodies:
Anime, video games and Nirvana(Version 1): Difficulty 2.5
Anime, video games and Nirvana(Version 2): Difficulty 1

Token Eastern Song: A rare Nirvana song on that's on the boxset. Both of my parodies were wrote to the live version because I'm more used to that version.

Parodies:
Token Eastern Song(Elgala Version): Difficulty 1.5
Nurse Witch Song: Difficulty 3.5

Anorexorcist: A song only played live, it's pretty tricky to parody. I've only done one to it.

Parodies:
Persocom Exorcist: Difficulty 3.5

Vendettagainst: Refered to as "Help me, I'm hungry" on the boxset, but some lyrics on the 4/87 version suggest that it is called "Vendettagainst". The only song I've done 3 parodies of, and the only song I've done parodies of two different live versions.

Parodies:
4/87 KAOS radio version.
Angel Brigade: Difficulty 3
Kiri Pro Resume: Difficulty 3.5
11/89 live version.
F*** me, I'm #orny: Difficulty 1.5

Breed: I had the idea for the parody of this song around a week or two before writing it, based it on Error. Nesplayer has a fixation with him and it in part inspired my parody.

Parodies:
I am Error: Difficulty 1.5

Beeswax: I love this song and have done two parodies for the fun and Challenge of it. It has very odd pacing, so I took liberties with it here and there.

Parodies:
Stephen's drunken Champloo: Difficulty 4
Calvin and hobbes: Difficulty 4

Mrs. Butterworth: This work in progress song I really like. The monologue in it alone was the main reason I've done two parodies of it. It is a very difficult song to use for parody material.

Parodies:
The Quest For The Fecal Matter Demo: Difficulty 5
The Reason I Should Never Write Parodies While Dru(nk): Difficulty 4

Drain You: My most favorite Nirvana song, I wanted to make a parody of it for awhile, I finally did and am happy with how it turned out.

Parodies:
Catgirl: Difficulty 4

School: For the fun of it, I did a parody of this simple song. It is based off of Please Twins.

Parodies:
Who is Maiku's sister?: Difficulty 1

Negative Creep: I got inspired to do a parody of this song by someone at livenirvana who said my obsession with anime was really creepy, it took awhile for the idea to kick in my head. It is the first song that I did a parody of in which I made fun of my own obsession.

Parodies:
Anime Geek: Difficulty 2

Swap Meet: I created a parody of this song a couple of months before finding out about amiright. I didn't finish until a few months later. It is one of my most repetitive parodies and is based on Excel Saga.

Parodies:
Across Conquest: Difficulty 1.5

Blandest: One of my favorite rare Nirvana songs. I made a parody of this song based on the anime Popotan and I make fun of myself for obsessing over the oldest sister "Ai" who has large breasts.

Parodies:
Ai, Mai and Mii: Difficulty 2

We Die Young: Red Ant and I had a parody contest where I did a Alice In Chains parody and He did a Nirvana parody. This is the first song I ever did that Nirvana never played and I made it about killing Scrappy Doo.

Parodies:
The Scrappy Doo Assasination Plot: Difficulty 2.5
(I misspelled the word assassination when I submitted it)

Pennyroyal Tea: I got inspired to do a Dragon Warrior parody based on this song. It wasn't too hard to make.

Parodies:
Dragon Warrior 3 Tribute: Difficulty 3

White Lace Strange And Strange: Nirvana played a cover of this song at KAOS radio 4/87, It's a Thunder and Roses song. I made a parody of this song about the Saiyan race from Dragon Ball Z. It was wrote in one night, but it was a fairly hard song to do one to because Kurt's vocals aren't very clear.

Parodies:
Saiyans: Difficulty 4

Stain: A song off of Incesticide, a dirty parody idea came to mind spontaniously when I was listening to it one night.

Parodies:
He's A Freak: Difficulty 3

This is how I rate my parodies in terms of difficulty.

Even in his youth: This song is on the Smells like teen spirit single. It is about sinus trouble, which I have.

Parodies:
I get sinus pain: Difficulty 2

Wet My Bed/Crackerman: I made one parody out of both these Stone Temple Pilots songs. This is my newest submission, and is mainly about Metal Monsters(from the Dragon Warrior series) with a touch of Please Twins!

Parodies:
Searching for metal monsters: Difficulty 3.5

Pen Cap Chew: A song that is on the box set. It is incomplete(only live versions are complete and I don't have one). I made a parody about the FCC to this song.

Parodies:
FCC: Difficulty 3.5

Old Age: An outtake from the box set. It was only recorded with scratch vocals which made it harder to do, I did vocal improvs of my parody idea probably well over 50 times before finally writing it. The theme is a medley of "Please Twins", "Azumanga Daioh" and "Popotan".

Parodies:
Please! Azumanga Popotan: Difficulty 4.5

Dumb: Came up with a "Urusei Yastura" theme for this song. I used the unplugged version to write most of it.

Parodies:
My Name Is Lum: Difficulty 3.5

Complicated: Went out of my territory here, wrote based on lyrics alone(although I have heard the original song 4 or 5 times). The pacing ended up being way off and the theme I used was done 16 times before me, so it wasn't well received(for more reasons than one). One Avril fan definetly didn't find it funny and told me so.
It was however, a good way to see if I could do a parody with just the lyrics. After finding out it had been done before I could've(and should've) changed the theme.

Parodies:
Avril's songs make me constipated: Difficulty 5+++++(and not worth it)

Sin: My parody of this song was posted today. Done for a contest between me and Red Ant, the parody is about the FCC. This is the 2nd song I've done an FCC basher to. Also the second(third if you count Wet My Bed as a song) Stone Temple Pilots song I have ever parodied.

Parodies:
My Opinion Of The FCC: Difficulty 3

Ain't It A Shame: Did a parody of this Leadbetter song that Kurt Cobain covered. The theme is a play on the original theme.

Parodies:
Ain't It A Shame Parody: Difficulty 3.5

Bleed The Freak: Did a parody of this Alice In Chains song, mainly about how others thought something was wrong with me.

Parodies:
See The Shrink: Difficulty 2

Sex Type Thing: The 3rd Stone Temple Pilots parody I've done. It is about the Please Twins! series.
(Just submitted today, should be up tommorrow).

Parodies:
Please Twins! Trilogy: Kousei's Thing: Difficulty 3

Rape Me: Came up with this parody after posting on the "Bump Me" and "Longest Thread Ever" threads on the "Playful Penguin Playground" message board.

Parodies:
Bump Me: Difficulty 1.5
