I'm a relatively good guitarist and have been playing for a few years, but I'm increasingly running out of new interesting songs to play. I play a bunch of different kinds/styles of music and I've written a few songs but right now I wanna "up" my Acoustic guitar Skills (Folk-Finger style,classical,something with some complexity not just another 3 chord progression) Do any of you have suggestions for some Good Acoustic songs to learn as to help me practice???
