Lesee,
I'm mostly listening to Classical and Blues/Swing/Big Band these days - John Lee Hooker, Muddy Waters, Squirrel Nut Zippers, Louis armstrong, Big Bad Vodoo Daddy, Django Reinhart, Fats Waller, Duke Ellington, Sam and Dave
As to Rock: Tragically Hip, Stevie Ray Vaughan, Jethro Tull, AC/DC, Pink Floyd, George Thoroughgood, Foo Fighters, Collective Soul, STP, Rush, Zeppelin, Eric Clapton, Cream, Hendrix, The Doors, Skynyrd
All time favorite Rock band would have to be THE WHO, has been since I was a kid .
As a general rule, I can't stand CCM. Although I liked the album "Jesus Freak" by DC Talk. I much prefer old Timey Gospel and Bluegrass, Mahalia Jackson, Flatt and Scruggs, Bill Monroe, Union Station, etc...
