One of the star applications launching with BlackBerry’s App World is Shazam, a music identification service that has recently found a home preloaded on some Samsung handsets. This is a very cool application: simply enough, you hold up your phone to some music that’s playing, and Shazam, through dark magiks and general witchery, finds album information, lyrics, similar tunes, and even buy the track. Very cool stuff overall. Hit up Shazam for more info, and if your App World happens to be in a good mood, you might be able to find it there as well.
