Acoustic Guitar Songs

What are some good, somewhat simple, guitar songs that I can learn to play on the acoustic?

I need some new ones to learn and preoccupy (sp?) my time.

Trailer Trash-Modest Mouse

I learned to play that the other day. Pretty easy.
Most songs by The Beatles are easy to play.
American Pie-Don McLean

I'll post some more once I think of them.
