Has anyone used Reverbnation for uploading songs or tunes?

I have seen uploads on other forums I'm on and I am wondering what anyone thinks of it. It seems to have a pretty generous upload limit of 100 songs with an individual limit of 8MB per song for the free version.

The info on the home page and the artists page is long on hype and short on hard info which is somewhat offputting but I did manage to get the above from the help page by putting in a question to the search box.

Before I sign up to these things, I like to know what I am getting.
