I am an avid fan of Utada Hikaru. I love everything about her music and personality. She's quirky and strange, plays tetris, and has a stuffed bear she calls Kuma-chan ("Bear").
However, before I knew all these things about her, I listened to her music. When I actually went to her website/blog and read a few things about her, I found that I became even more of a fan because I found her personality so insanely cute.
So, does the personality of a singer/band influence how big of a fan you are of theirs? If the singer/band played about views you disagreed with, or did something wrong (ie. Michael Jackson) but still made music you found very good, would you still listen to them?
