Jimmy Buffett: Beaches, Boats, Bars and Ballads - its not all of his best stuff, but if I had to pick, that set would be a good representative of things
Carole King: Tapestry - What and *amazing* disc - I can't say enough about how much I love it. AND one of the songs is used as the theme to Gilmore Girls (I love that show!)
Cowboy Mouth: Are You With Me? and MercyLand - an awesome group of New Orleans boys that hit it big! Great CDs for a mellow mood
