I pretty much will listen to anything as long as it's up-beat, otherwise I'll fall asleep. I really can't stand rap except for a few songs (and I can't tell the difference between rap, r&b, and hip hop

)
I only listen to a few songs over and over (well, I don't listen to some of these anymore.. they're more of my summer songs)..
justin timberlake- senorita, cry me a river; john mayor- neon, no such thing; good charlotte- loser anthem, lifestyles of the rich and famous; avril lavigne- i guess all of her songs; amy studt- just a little girl; oar- crazy game of poker; madonna- die another day; eve6- heres to tonight; foo fighters- all my life; hoobastank- remember me; the theme song to alias; a song from the matrix; jewel- standing still; jimmy eat world- sweetness; josie and they pussycats- pretend to be nice; the red hot chili peppers- cant stop; maroon 5- harder to breathe; and the all american rejects- swing swing
i also like weezer's keep fishing, and the sweater song, minuet in g, and all of the barenaked ladies songs

oh and I forgot tatu's all the things she said, and blue monday's orgy.. and tony bennett's the best is yet to come, frank sinatra's fly me to the moon and high hopes
