What are some good songs to upload to my ipod?

I have Aerosmith, Evanescence, Flyleaf, AFI, Blue Man Group, Offspring, Papa Roach, Panic at the Disco, one song by Lady Gaga, Fall Out Boy, Lady Gaga, "Edgecrusher" by Fear Factory, Slipknot, System of a down, Breaking Benjamin, Three Days Grace, Avenged sevenfold's "a little piece of heaven" (lost my cursed cd. :'( ), Motely Crue, Guns and Roses, Crossfade, and a few other bands. Any good songs along these lines? I'm ok with rap, if I hear the song first. :) (Gonna check em all though). I still have like 150 songs left (and some I need to delete). All suggestions welcome. Country...is ok. Picky with it, but it's ok.
