Did the upgrade and still says it's unlimited for me. Yay! The new version also seems to add a lot of functionality.
The program is amazing....I was astounded it could pick out songs even in the background of noisy stadiums, restaurants, hockey arenas, and most recently, in a crowded school auditorium full of screaming people.
I have only had one song it hasn't recognized, which was a song at the closing credits of Flashpoint (the tv show). But Soundhound didn't know it either (although on the second attempt at Soundhound it misidentified the song as some Rihanna song, which I knew it wasn't). So I did some Googling and found out it was "Let it Go" by Daniel Cage. So off to MP3 Downloader and it couldn't find it either.
Grrrr....so all 3 apps failed me on that one song.
