What new GOOD music is there?

I LOVE music....but the radio sometimes plays the same songs over and over again. I would look for good music on myspace, imeem, etc. but my parents keep a limit on my internet usage. I use my sidekick for the internet but can't listen to music. Musicians that aren't that famous yet but have good music are cool with me, or musicians from other countries that sing in english. :) Can anyone give me a list of songs to check out once I get on the computer?? I like artists like T-pain, alicia keys, boys like girls, fall out boy, all time low, kayne west, panic at the disco, the red jumpsuit apparatus, paramore, uffie, adam tensta, bridget kelly, my chemical romance, jay-z, linkin park.
