it's
www.remix101.com
the basis is for DJs and music producers to upload their remixes of songs. of course, these files naturally come in 5mb or more. hence, they need a 3rd party hosting service. at the moment, i recommend people to yousendit, rapidshare or sendspace, etc.
inside the forum, people who love dance music or other DJs can download, listen and give feedback to their peer's work.
the site is only a month old, and i'm about to start marketing it heavily and doing a lot of cross-promotions with it.
