Readers' Poll: The Best Songs of 2012

The Black Keys had a real tough time figuring out how to record "Little Black Submarines." A hard rock approach didn't seem to work, but they didn't want the entire song to be acoustic, either. In the end, they decided to merge the two. It begins as a gentle ballad before drummer Patrick Carney kicks in and the song takes off. It's like a compressed "Stairway to Heaven." Rock photographer Danny Clinch shot a video for the track, and although the song didn't manage to crack to the Hot 100, it has remained a fan favorite.
