just looking for more acoustic "feel good" songs to just play around with. Anbody have any suggestions?
Country Roads by John Denver. Dont laugh.. its the first song Kravitz learned to play. Its in the key of G and you can speed it up and jam on it a bit. Doug E Fresh does a hip hop cover of it at MSG for the NY Knicks.

Another easy feel good tune is Stoned Me by Van Morrison. Also in G and very simple.

also most everything from the Joshua Tree translates quite well to acoustic.

Of course none compare to the greatest acoustic feel good song ever....
