I know I'm going to cause a riot(but isn't that why we have a message board?
1) Jimmy Buffett - 2 songs don't deserve a restaurant, 25 years of continuous touring, and a lifestyle/wardrobe.
2) Dave Matthews - Jimmy Buffett 2.0, just with a few more songs. His songs are okay, but the cult following is obnoxious. His concerts seem like an excuse to relive your freshman year of college.
