If you lost your whole music library except artists that start with 1 letter what letter would it be? I used to think 'M' ... Mew, Mogwai, Muse, Mewithoutyou, MuteMath, Mumford & Sons, Mono ... but I think I've changed my mind. B is dominating my music life right now... Bon Iver, Black Keys, Blakroc, Broken Bells, Bon Iver, Beastie Boys, Band of Horses, Bon Iver, and Balloon Messenger. Yes, I know I said Bon Iver 3 times.
