Listen to some OAR, sublime, and of course bob marley.

Bob Marley:

three little birds

Sublime:
40 oz to freedom
smoke two joints
Badfish
Santeria
Caress me down
Garden grove
Date rape

OAR:
Sometimes i drink
Hey girl
About mr brown
Night shift

The drums and bass usually drive the song more than the guitar does. You will prolly want to just learn the techniques used not so much the whole songs. They are kinda boring to play without the rest of the band.

Well I was going to post.. but evantsut7 just stole my suggestions. I would disagree that it's boring all the time though. A lot of songs, yes. But some reggae acts like sublime do have a lot songs with interesting guitar too.
