"You've gotta live in this world," the great Joe Strummer once sang, "and go diggin' the new." At Diffuser.fm, we couldn't agree more. That's why we're adding new songs each week to our online radio station. Don't worry -- we're not getting rid of your old favorites. Diffuser.fm. Radio still boasts an eclectic mix of modern and classic alt-rock and indie jams. We're simply peppering the playlist with a few fresh platters -- or digital combinations of ones and zeroes, if you want to get all technical.

This week, U.K. rockers Bloc Party rumble through the Nirvana-esque 'Kettling,' enduring pop-punk heroes Green Day cut loose on 'Let Yourself Go,' Americana outfit the Lumineers ramble through 'Stubborn Love' and Icelandic folk rockers Of Monsters and Men aim to raise spirits with their aptly named 'Mountain Sound.'
