I had to make an account before I could actually find out the payment/subscription details, and only after getting that far did I discover that the "web-player" requires a special streaming plugin with no Linux port.
None of this was helped by the website being godawfully slow to do anything, and it popping up a box asking me to install the plugin every 10 seconds when I wasn't even trying to play music.
Finally I get sick of all of this and try to delete my account, which is, as far as I can tell, impossible.
