Interesting.. – Guitar Tunes™ Review

From $2 -$15 , what do I get for $3 , $9 ,$15 ??? Such a high cost too find out if app is good or not. What about AC/DC & Black Sabbath , Metallica,songs? ... didn't see them.. Can you video it on how app all works ? The play button on your profile pic don't do anything..
