A couple of my favourite artists have tended to repeat popular lyrics from an earlier song, in a later song of theirs. For example:

The Police - Every Little Thing She Does Is Magic
and
Sting - Seven days
both contain the verse:

"Do I have to tell a story
Of a thousand rainy days since we first met
It's a big enough umbrella
But it's always me that ends up getting wet"

also

The Smiths - You Just Haven't Earnt It Yet, Baby
and
The Smiths - Paint A vulgar Picture
both contain:

"You just haven't earn't it yet, baby''

Also, numerous songs contain lyrics from 'Hand In Glove' as Morrissey was obsessed with putting lyrics from that song everywhere, so that people would hear it constantly. Are there anymore? I think this could be interesting if there are :)

???  Didn't AC/DC have a song or two on two different albums?  ???

The first two Australian-released AC/DC albums were repackaged for worldwide release, and the international version of 'Dirty Deeds' has a different track listing to the Australian version, but unless you're one of these blockheads who contends that all their songs sound the same anyway  ::), all of their albums have different songs on them.

Ronnie James Dio makes a lot of references to rainbows.

He started back when he was singing for Rainbow, but I'm still hearing the references in his solo work.
