I'll delete songs I'm embarrassed I owned, but that's about it (and I don't even delete all that, I have frickin' Smash Mouth songs on my computer after all). I figure if, for some reason, I don't play a song, I can always leave it there in case someone else wants to listen to it.
Smash Mouth?!?
I think i can beat that in "guilty pleasure" music wise...
I have this as mp3:
Una Paloma Blance
OK, you win
