what are some good bands to make a cd for my first girlfriend?

She had me make her a cd before, i put things like demi lovato, couple similar singers... she just recently said "you should make me another cd!" but i'm not sure what to put on it this time! i want some like... sweet songs on it.... i put "guardian angel by the red jumpsuit apparatus" on my playlist for the new cd, and a breaking benjamin song, and one by story of the year... anyone know any good similar songs/bands? i dont want to make her a bunch of cds with demi lovato on them(we both love her but i want it to be different!)...

thanks!
