Has anyone downloaded this free app yet? I just did because my friend recommend it to me and I am really glad I did! I have been explaining to her how hard it is to find a good music app but she definitely proved me wrong with this one. Six String is not about tapping to the beat of the song but you are actually playing the guitar! If that wasn't cool enough, not only can you play songs from Bon Jovi and affinity artists but you can purchase additional songs I really recommend http://bit.ly/bLJxVA
