I have been listening to Nine Inch Nails lately, who else might I like?!

I have been listening to Nine Inch Nails lately, who else might I like?

I am not really looking for mainstream music. I am also a big Tool fan. Any suggestions?

go 2 pandora.com and search both of those artists
it will give you a playlist of other songs that you might also like

i have searched them 4 u and come up with these rsults

tool: mudvayne, audioslave, a perfect circle, godsmack
nine inch nails: marilyn manson, KMFDM, ohgr, robzombie

hope i helped
