In the past, I had always kind of passively listened to their singles, but ever since I've heard Feel Good Inc., I haven't been able to stop listening to them. They manage to pull off something special with the blending of all the different styles and the great characters.
So who's you favorite character? Song? Video?
A side note: I think it's funny how much the creators of the band (primarily Damon Albarn from The Verve and Jamie Helwett, the artist of Tank Girl) have managed to pull off so convincingly that the band members are real, breathing people, and that the videos are just avatars of the real people. I've been to sites where people are doing in-depth analyzations of their songs, quoting the "band members" from the official site, taking everything so very seriously...not realizing that it's just a very clever way of the creators to trick them. Regardless, the characters are very interesting and show quite a bit of personality in the videos, and even moreso if you visit their website, which is a highly interactive flash version of their "studio." Worth checking out.
