Like ladykillers with songs. This was what the "songs you might recognise" thread soon became thanks to BB_Eye's revelations

(M.I.A.'s Born Free being a sample etc.)
Basically post songs that have unabashedly stolen from others in an attempt to demean their worth.
Example
#1:
Radiohead's "Karma Police". You should recognise it.
has an uncanny resemblance to a song from a little-known band called The Beatles. "Sexy Sadie":
Example
#2:
I posted this in a separate thread not too long ago. The Verve's "Bittersweet Symphony" should be something you know.
BUT WHAT'S THIS? A string version of a Rolling Stones song.
and my final offering.
#3:
Rogue Traders' "Voodoo Child".
not only did it steal a name of an already known song, but it nicked a bit of Elvis Costello too.
