Increasingly I've been finding more and more people are out there on SoundCloud. So I've joined them, clearly MySpace seems pretty much long dead and Reverbnation whilst good is looking a little old and haggard in the fast paced changing world of music dissemination.
Anyways I've a profile and a bunch of tracks up at http://soundcloud.com/grahamhunt-1 please pop over and say hello.
One thing with Soundcloud is that it very much is a mix of producers and consumers - there are a huge number of people on there simply using it as an on-line music juke box - which has been a restriction with Reverbnation for me the only people who join up are normally other musicians, Soundcloud looks a more direct to consumer method.
Having said all of that of course - if I ever get to 100 plays I'll be happy! :-)
