Wow... Great list!!!!! Some of my favorite songs are on your list!
Maybe [I]Crazy Train[I] by Ozzy Osbourne?
Life is Beautiful by Sixx:A.M.?
Just a few suggestions...
If you only make recent and hard rock DLCs, you'll only have customers who like that music. The forums will be full of people who ask for more of that type of music. Try reaching out to new customers. Bring in some good R&B groups. also, challenge your existing players to play some harder beats like James Brown, Average White Band, Isley Brothers, Brother's Johnson. The Brother's Johnson will make people start liking the Bass.
