fugazi - sieve fisted find has this bass part (in the "please let me get my hands on it" part) that reminds me of kool thing
toadies - tyler / pixies - where is my mind
interpol - say hello the angels / the smiths - this charming man
every other interpol song / joy divison - shadow play
I know I'm forgetting some, but I ALWAYS hear songs that sound like, or at least remind me of, other songs in some part... hmm.
