Query: He just keeps getting better...

I will buy any of John Mayer's albums because it is rare to find an album where you actually enjoy each and every song. John keeps changing his sound and getting better. This album is more "bluesy" than his previous releases and is great! I especially love "Slow Dancing in a Burning Room" and "Heart of Life." A definite must have for anyone who appreciates REAL talent.
