Ive been playing guitar for about 5 years now and im looking for some challenging acoustic guitar to learn. Id prefer finger picking songs like classical gas but im open to pretty much anything.

If i could get some suggestions of good acoustic songs to learn that would be great. Anything would be appreciated.
i dont know if it is challenging enough for you, but it sounds sweet, its called "warriors of Time" by Black tide, but its more like hard rock/ metal than classical.

Bass: Yamaha RBX170
Amp: Fender Rumble 100
Pedal: Boss BOD-3 Bass overdrive pedal
