If you haven't heard, Bjork celebrates her 49th birthday today, and we have been bumping the Icelandic singer's music all day. Hopefully, you've already gone through the Singer's Craziest Looks. But if you need an excuse to listen to, or revisit, the singular musician, we've compiled this 49-song playlist, including classics, rarities, remixes and tracks from her pre-solo band the Sugarcubes (including, of course, their hit "Birthday.")
