A Perfect Circle- Judith, Rose, The Hollow
Tool- Cold and Ugly, and a shitload of more songs i dont feel like naming.
In Flames- The Jester Race, Moonshield, Artifacts of the Black Rain, December Flower, Gyroscope
Metal...oh, where to start. I'll assume you've heard of Iron Maiden and are familiar with their catalog, so I'll move on.
A band I'm diggin' right now is Primal Fear. Old school metal sound, a lot like Judas Priest with speed metal riffage. Too sweet if you're into that stuff. Check out their albums:

Devil's Ground
