I thought this application Ocarina was pretty innovative. It has a very cool mapping/listening mode and Midomi that is Shazam-like but over and above listening to a playing song, it lets you sing a snippet, announce the name of the song or type it to then get a screen showing you artist info, youtube and itunes links and the amusing plus of listening to other users singing snippets.
