Lamb of God, I especially like the concert dvd they have out called Killadelphia. In between the songs they have stuff the band is doing that is sort of interesting, in one Randy, the drunk singer, gets in a fight with Mark, one of the guitar players. Or, once you have seen that stuff a couple times, you can just play the dvd - music only. I play guitar and they are really hard to copy for me. Ever so often I throw that disc on and rock the house. You might also get yahoo radio and set up a station for heavy metal if you are at the computer a lot, or if you have satellite radio in your truck you can listen to hard attack on sirius or liquid metal on xm and get some ideas.
