Not that the concert app market is lacking, but we wanted to point out Songkick to the music buffs in the building today. If you hate to manually keep track of your favorite artists and when their next concert is happening, this is the app for you. Upon installing, it scans your music library, Google Music account, and Last.fm app to figure out who you like to listen to. Once it has a grasp on the situation, it starts notifying you of incoming concerts that you can add to a calendar or pick up tickets to. From what I can tell, it does a hell of a job, aside from that Bieber addition. You can also add specific locations and see what concerts are on the horizon or see what other cities your favorite artists are playing in.
