I have the new Nickelback CD along with previous Nickelback CD's and they are really good. Granted I wouldn't want a kid under 16 or so listen to some of the songs, but you can always burn a cd minus a few of the songs and all is good!
I also like Bowling for Soup, Angels & Airways, Evanescence and I just got the Breaking Benjamins Cd.
If you like John Mayer....I would recommend Five for Fighting.
For those of you who like music like Frank Sinatra and Michael Buble, I recommend the new Rod Stewart CD - It had to be You.
