Hmm, well here's a few good songs that have some good acoustic guitar in them:

1. Diablo Rojo- Rodrigo y Gabriela
2. For Mom (Early Version)- Buckethead
3. Civil War- Guns N Roses
4. A Place of Springs- Phil Keaggy
5. Mama, I'm Coming Home- Ozzy Osbourne

I hope these songs will help, I like all of them a lot anyway. Cheers!
