What's an awesome band/singer/song?

not mainstream preferably, and also not the crappy popular stuff nowadays like usher and jason deruelo...I want something like rockish likee the old greenday, but something underground. I also like the original escape the fate (before they went screamo), mcr, avenged sevenfolr---something like those would be aweosme. i need the songs for my ipod which is a bit empty atm...
