Thanks for the feedback. To answer some questions:
The Wii player is a beta, but the actual system is out and available now. You can find it at www.finetune.com. Finetune is one of our clients, we built the flash based player on their site as well as a version you can embed on a blog. The one for the wii still has bugs, but we will keep working on it. Thanks for the feature suggestions, we plan on adding features as it rolls out. As for how they make money, right now they are building listeners. They will eventually make money through things like sponsorship. For example, maybe Coke can bring you the Wii music channel. Right now it's free. And 100% legal, thats why you can't play a specific song or go back to a previously played song - it's part of the music licensing.
