Has anyone checked out this site yet?
http://soundcloud.com/It a new site that's being setup with the distribution of music in mind. It's got the traditional upload and post your tracks for users to listen to, along with a smidgen of social networking. The pop-up comments on tracks are a bit amusing.
It's also positioning itself as an alternative to YouSendIt, by allowing people to send out tracks within the system via distribution lists.
And lastly, it's got a dropbox widget that bloggers can add to their sites, where artists can submit tracks directly to them.
Pretty cool as it supports a wide variety of digital files including AIFF and the artist can allow public tracks to be downloaded.
I finding searching of specific genres a bit tedious partly because it allows for self tagging of tracks. It's a bit heavy on the bedroom electronic music producer/DJ at the moment. But, that's kinda always the case with these types of sites.
It's still in development but a pretty cool site in general...
