Help with Music suggestions?

I want to make a mixed CD for my bf (Cheesy I know) but I'm not sure what type of music he's interested in really besides what he told me. The things that he likes (from what he told me) are songs from Linkin Park, My Chemical Romance, and Globus... I was wondering if, using those three artists, that somebody could suggest other artists that would be interesting? ----- Thank you so much :)
