I picked Friends, but I do love Alias. It's my ringtone and everything. I also like Everwood's opening. It's got lots of violin and it's really pretty. ^_^
OMG! I love the E.R. theme! I don't really watch the show, but I always tune into the beginning just to hear the song. Alias's is pretty cool too, but I like the old one better.
BtVS has a fantastic theme song - but only beginning season three. Otherwise the OC wins - although I cant stand the editing of it. Lol - am picky about music.
