What it is?
Unlimited Beta means that we're in our initial launch phase. There are more features on the way. Until those features arrive, all accounts get unlimited songs for free.
In the future, we may add paid accounts. When the time comes, we plan on looking at our user base and finding out how much our hardcore users use the site. They're the ones we'll be targeting for paid "premium" accounts. The accounts will be inexpensive, too. We're guessing around $2.50 a month, but that has yet to be decided.
At any rate, enjoy the site and please report any bugs to us at info@REMOVEMEgetyourgroREMOVEMEoveon.com.
