just wondering if anyone could recommend any songs that are fun and funky acoustic songs. Sort of like the intro to crazy on you by heart.
I am the drummer.
Not as fast and funky as crazy on you, but if you play "Hey Hey" by Eric Clapton really fast it sounds cool. It is from his unplugged album.

EDIT: Also, no where even near as fast as crazy on you, but "Why Georgia" by John Mayer is funky.
What Would You Say - Dave Matthews Band

DMB has a ton of funky acoustic stuff.
