Awsome Rhythm game!
I love how you made the notes actually synch to the music, and the notes that are being played almost always match the notes in the song. This shows that you've really taken the gameplay into consideration heavily.
The selection of songs were pretty good for a guitar game, they all had good rhythm and suited the game well.
The only thing that could have been improved were perhaps the animations while playing the guitar, you could have added more variety to make the game look more flashy but its still pretty awsome.
Best rhythm game i've played for the rock out contest so far! way to go!
