[UPDATE: Shazam is now available for blackberries running 4.2 OS or later!  Go to mobile.blackberry.com from your phone and install the app store application from which you can then install many apps including, at long long last, Shazam]

I really really wish someone would develop this and BB would support it. Sadly it does not exist for any current blackberries. Nobex Radio Companion will tell you what is playing on any radio station, but won’t work with an ad hoc song.
