I Feel Love by Donna Summer - from 1977 but sounds like it could have been released even as late as the late '90s(with updated drums)
Voodoo Ray by A Guy Named Gerald - '90s style rave music made in the late '80s
Most Kraftwerk from the '70s
Debaser - by The Pixies - basically '90s alternative rock at it's fullest
Shaft by Issac Hayes - sounds like a more mellow disco song even though it predates the trend by about 3-4 years
Believe by Cher - first autotuned pop song
Bling Bling by Cash Money Millionaires - sounds like mid '00s southern rap(released in 1999)
Make Em Say Uhh! by Master P - basically primitive crunk music from 1998, could have been released in 2003-ish
The whole Low album by David Bowie - influenced tons of new wave artists
Satisfaction by Benny Benassi - from the early '00s but predates the early '10s electro-house sound
Get Ur Freak On by Missy Elliot - sounded alien when it first came out in 2001
Epic by Faith No More - predates nu-metal by a decade
The whole Control album by Janet Jackson - released in 1986 but leads the way to new jack swing sound of early '90s
Let The Music Play by Shannon - one of the very first freestyle songs, sounds like it was released in 1988(released in 1983)
Single Ladies by Beyonce - sounds so futuristic and metallic, like a 2085 song released in 2008  ;D
Whine Up by Kat Deluna - a 2007 song that could be released in 2011, has the modern RedOne, Lady Gaga style synths
You Really Got Me by The Kinks - basically the DNA for all punk music
The Inspiration Information album by Shuggie Otis(maybe a tie with Sly Stone and the Family) - early drum machine, a 1974 version of Prince
Most Talking Heads from the late '70s/early '80s - most '00s disco-punk/indie bands took from them(LCD Soundsystem, Franz Ferdinand)



I'll add more later.....

'Eighties' by Killing Joke.  1984 this came out.  It just baffles me.  It is like they knew what the 90's were gonna sound like.

"Back That Azz Up" by Juvenile (1999) sounds like a mid 2000s song.
"Toxic" by Britney Spears (2004) could have been a 2009 song.

West end girls- Pet shop boys. 
Was huge in 1984, but could have fit in well well in the late 80s.

That's when synthpop started to turn more into dance-pop, maybe around 1986-ish.

Wouldn't sound out of place in 1993(maybe slowed down a little).
Reminds me of Come As You Are by Nirvana.

The Beatles - Tomorrow Never Knows (1966)

http://www.youtube.com/watch?v=6a3NcwfOBzQ

Golden Years- David Bowie (1975)
This song would almost fit on his "Let's dance" album from 1983

http://www.youtube.com/watch?v=wd2clb5T8JA

It's funny you say that.  When Nirvana released 'Come As You Are', members of Killing Joke claimed a similarity, and apparently tried to sue, but the lawsuit was dropped when Cobain died.

John Cage: 4' 33"
http://www.youtube.com/watch?v=HypmW4Yd7SY
Ahead of its time in 1952 and still ahead of its time today!

Pierre Schaeffer: Etude aux chemins de fer (Railroad Studies) (1948)
http://www.youtube.com/watch?v=N9pOq8u6-bA
Schaeffer is called the father of Musique Concrete

Steve Reich: It's Gonna Rain, Part I (1964)
http://www.youtube.com/watch?v=TY3W4Lwr-I4
Tape phasing technique.  Part II

Charles Ives: 3-Quarter Tone Pieces (1924)
http://www.youtube.com/watch?v=EU85bUyDPWs
Early microtonality in Western Music.

Henry Cowell: The Banshee (1925)
http://www.youtube.com/watch?v=ND-ga_BrkCE
Employs the sweeping, plucking, and scraping of piano strings.

Lou Harrison: Fugue for Percussion (1941)
http://www.youtube.com/watch?v=oZ4abheV9ts
It was still rare in 1941 for percussion to be the sole ensemble, or even a leading instrument
in Western music, let alone with the instruments and scales Harrison uses here.

John Cage: Bacchanal (completed 1940)
http://www.youtube.com/watch?v=SwJLGUgs1jc
Cage's first work for "prepared piano."  Cage wanted to do a piece for
piano and percussion group, but the performance space did not allow room
for percussion, so Cage "prepared" 12 piano strings with weather stripping to
give them a more percussive sound.  The piano only allows for whole tones and
semitones.  Ives used detuning earlier to get quarter notes.  Cage and then
other composers used objects such as nuts, bolts, glass, and screws to attain
microtones from the piano.

Milton Babbitt: Compositions for Synthesizer (1961)
http://www.youtube.com/watch?v=gbzw8VNkA5o
While the first "electronic" music composition is debatable, Babbitt set the
standard for excellence on the RCA Mark II electronic synthesizer at the
Columbia-Princeton Electronic Music Center in the early 1960s.  This was
pre-Moog.  A synthesizer composer had to be part artist, part engineer, and
part studio technician to make all those cards, wires, and switches make music.

James Tenney: Ergodos I (1963)
http://www.youtube.com/watch?v=EeTkEP6EmL8
While Max V. Mathews is credited with writing the first digital computer music
software 1957, it was James Tenney at Bell Labs in the early sixties who
made the first truly aesthetic music with it.

While most pre-1965 electronic music concerns itself with scientific research
and high art, Raymond Scott was an early proponent of creating pop music with
electronics...and he did.  Here is an Cyndy Electronium from 1959
http://www.youtube.com/watch?v=1SHJ6CcML80

This song was released in 1979, but it sounds very '90s to me.

http://www.youtube.com/watch?v=ExYsh1W22Wo

http://www.youtube.com/watch?v=cjco1bDg20Q

here's a carefree morning-in-america tune from 1979 that makes me wanna vote for ronald reagan. and believe me, that takes a lot.

Talking Heads - "Once In A Lifetime" Recorded 1980.

http://www.youtube.com/watch?v=I1wg1DNHbNU

Many of their songs would fit within this thread.

Yeah I already mentioned them, they influenced not only the indie dance bands of the '00s but alot of the '80s world music too.
Well I promised more so......

Weezer mid '90s period - anticipated the '00s emo music
Sgt Pepper album by The Beatles - influenced alot of '70s rock like ELO and Queen, from the music hall of When I'm 64 to the muti-part suite of A Day In A Life
Video Killed The Radio Star by The Buggles - one of the songs that kicked started the '80s, first video to play on MTV, constantly confused as an '80s song(released in 1979)
Little Miss Lover By Jimi Hendrix - one of the first funk-rock songs, anticipated '70s funk bands like The Isley Brothers and Funkadelic
Rage Against The Machine early '90s period - would not sound out of place in 2001, predated the nu-metal trend
Todd Edwards mid '90s period - predated the early '00s UK garage/2 step by 5-7 years, very unique cut and paste sound
What I Am by Edie Brickell & The New Bohemians - released in 1988 but sounds like it's from 1994
Pump Up The Jam by Technotronic - a 1989 song that could have been released in 1995, one of the first popular eurodance songs

I'm sure there's going to be tons of 2009 songs that sound like they could've been released in like 2015 by the end of this decade(in hindsight of course).
That year just brought in a new feel, a more electronic, poppy sound, and the faux-gangsta and post-grunge trends were finally fading away that year too.

Sly and the Family Stone - Thank You (Falettinme Be Mice Elf Agin) 1969   

http://www.youtube.com/watch?v=des0hOyzgRs

Sounds like mid 70s funk.

After watching Madonna's Express Yourself video(it's from 1989), it looks like it could have came out around 1996-ish, same with the music too.

This was at least 5 years ahead of its time.
