Add any websites that often have new bands/songs. For some new indie I usually search here:
Pitchfork
http://www.pitchforkmedia.com/
I don't use them so much anymore, as they only seem to promote already semi-famous bands or bands you'll never hear about again and can't pronounce.
Blisspop
http://www.blisspop.com/
Blisspop is a monthly DJ show in some dance club, or something like that. Even though I'm not entirely sure what they/it is, I do know they supply me with some good, new tunes. Click on Playlist (the headphones on the right, second picture down) and you'll get a nice smattering of free, new indie and dance musics.
Video-C
http://www.video-c.co.uk/
Video-C is a British website that often has new bands and artists just hitting in the U.K. Typically they get the good stuff MUCH earlier than us, allowing you to TRULY be indie and find things before your friends and MTV. Over the years, I've found Lily Allen, The Bravery, Kaiser Chiefs and many others on Video-C WEEKS before I hear them on TV or the radio. Do some digging though, the good stuff's not always on the front page.
