Marilyn Manson is a good metal band?
I started listening to Fleshgod Apocalypse a couple of years ago. They are INCREDIBLE, and just keep getting better with every new album. It's an awesome thing to watch them evolve.
I like Marilyn Manson, but I've always thought of him as more of a hard rock / industrial / shock rock sort of thing. If you're into that, then I guess you would like anything from Nine Inch Nails, Gravity Kills, Stabbing Westward, Godhead, Dope, and a handful of others.
I LOVE Marilyn Manson.<br />
I don't know if they're considered metal, but I love Korn, Slipknot, Nine Inch Nails and Disturbed as well.
