I have weird tastes in music-- meaning, I like weird music!
I like parodies/spoofs and "novelty" songs like the things they play on Dr. Demento. I don't really keep that "secret" though! The strangest things I like are probably Jingle Bells by the singing dogs and "Fish Heads" by Barnes and Barnes.
Some of my favorite artists are ones who have weird/silly songs like Weird Al, They Might Be Giants and the Presidents of the U.S.A. I've been to several Weird Al and TMBG concerts, those are two of my top favorites. I also really like Oingo Boingo, Fall Out Boy, All-American Rejects, Evanescence, 80s music, horror movie soundtracks...
Oh and I love this song: http://www.jonathancoulton.com/mp3/R...r%20Brains.mp3
