Don't know if this counts but: I think Michael Jackson is innocent. Edit: I want to note I didn't follow any of it. So I believe that just because I want to.
I personally think that MJ is innocent too... I listen to Thriller every night, and dance to it too. xD
For a movie, Across the Universe and I guess the music from that would honestly be a guilty pleasure as well.
I enjoy telling-off people who think blind people are at a disadvantage when it comes to learning music.
I like the Spice Girls...even tried to buy tickets to one of their concerts once but it was sold out already.
