it is of the genre of Nickelback, Daughtry,etc....pre-packaged, mtv friendly, "rock by numbers" music that doesn't have much substance.
do your kid a favor and buy them a Tool album, or something from another band that has original music and lyrics that promote a little bit of self reflection.
EDIT: I just went back and saw that your kid is 12. maybe wait a couple years on Tool. not that the lyrics are THAT bad, but it's more adult oriented content.
