Query: It's not supposed to be his music, stupid

This is just another in the great "Pickin' On" series, AS IT SAYS ON THE FRONT. If you're too dumb to ask for help, don't expect us to feel sorry for you. This has 9 of John's songs redone in bluegrass, and tastefully so. I would recommend it to any fan of Mayer's; if you have extremely narrow musical interests, you can always try it out and sell it if you don't like it. Or you could whine about it on the internet. Also, check out Jack Johnson's Pickin' On album. It's great as well.
