I'm using it - http://chunks2.bandcamp.com/releases
but it hasn't helped one jot yet. Not a single purchase and I have no idea if people are even listening to it streaming.
If you log in and make sure you're on 'desktop mode' you should be able to click on the 'stats' link and see how many people are listening. I agree 100% with what Kid said as that's been my experience as well.
