I over heard a guy talking at a coffehouse yesterday who said "I used to hate this song, but now I love it." I felt compelled to turn around, barge into the conversation, and ask "What made you change your mind?" Luckily he didn't take offense to the interruption and appreciated my interest. After thinking he decided that at some point he had actually paid full attention to the whole song and realized it wasn't what he'd been assuming from superficial listenings. I think this switch from hating something to loving it is a very interesting emotional dynamic. What did you used to hate that you now love, and what made you change your mind?
