SongKick is a concert listings site that has created a comprehensive database that tracks concerts as they appear on 14 different ticketing sites and across dozens of blogs. You can search the database and track shows and blog posts about your favorite acts, or download SongKicker, which automatically tracks artists you listen to. SongKicker is a plug-in that pulls artists you listen to from iTunes, Windows Media Player, and Winamp. The process takes about 3 minutes and adds the artists to the tours you’re tracking.
