Jimmy Buffett

One Buffett agreed to write a song, Shelton immediately committed to using it as the 'Barmageddon' theme -- before he even heard it.

He sure knows how to enjoy the good life.

On Aug. 9, 2003, Jackson and Buffett hit No. 1 with "It's Five O'Clock Somewhere," from Jackson's 'Greatest Hits II' album.

Alan Jackson wasn't even second in line!

The Boot takes inventory of the best tracks to blare as you're headed to, sitting on or just dreaming of the beach.

Cheers!
