I would use this service if:<p>1) Only an email and password were required to use it (I don't use facebook).<p>2) It were robust, reliable, and fast; artists without a label or a consistent way of publishing songs shouldn't be a problem. In other words, if I can't rely on this service to track all the artists I listen to, its value significantly diminishes for me.<p>With that said, I realize you're in beta, and you're off to a great start by addressing a real problem.
