If you need some rock song ideas...personally I like :
Alter Bridge- "Shed My Skin", "The End Is Here"
Sevendust- "Angel Song" "Follow"
Chevelle- "Vitamin R"
I don't know if that is what you are asking. Those are some songs that I dig. Those songs and artist. I have to change my style up once and a while and I like zoning with those artist.
