Rolling Stone put together a list of the 20 Frattiest Bands.

They did it just in time for spring break.  The list features a few surprises, but some of them are pretty obvious.

Dave Matthews Band makes the list.  Rolling Stone writes, "there is no question that they are most responsible for sparking frat-kids' migration toward Jerry Bears and Bonnaroo," as their reason for DMB's place on the list.
