A Deal-Breaker, for sure.

I once went on a date with this guy and things were going great until we got back to his place and I saw that his CD collection featured Sublime, Creed and ICP rather prominently. I then had to form a graceful exit strategy claiming "womanly" things. He called me a week later and I let him go to voicemail.

For awhile I felt bad about this until I realized that Music Nerds can and should only date other Music Nerds. It's a safety thing; god forbid you begin to get a little personal and he decides to play "When You Look Me In The Eyes" by The Jonas Brothers in place of anything by Zero 7, M83, or even Prince (all of these acceptable choices. Nothing kills the mood quite like a tune produced by the Mouse).

To further incriminate myself as a Music (Snob) Nerd, there are certain friends of mine at whose parties I always arrive with a fully charged iPod; spending the precious early moments of socialization and imbibery by lurking about the speakers in the corner waiting for that perfect moment to unplug the Pre-Made Party Playlist and usurp the offensive musical power with my own carefully constructed list of tunes. Catty? Very much so, but one can only handle so many exclamations of "OHMYGOD I loooooooooove this song." Before an even-worse-than-the-original-although-I-never-in-a-million-years-could-have-dreamed-that-was-even-possible rendition of The Pussycat Dolls' "Don't Cha" is performed to the delight of nobody.

I consider my actions to be of a great boon to society and ear canals across the board.
