QTrax, the start-up that only days ago was promising 25M legally-downloadable songs, doesn't have any deals signed with major labels after all, but today the company has made its player available. It's a re-skin of the open-source player Songbird. For now, you can only play music from your own computer (or, thanks to the built-in browser, from a web site), but there are already plenty of ads. The Samsung banner opens this page in a separate tab.
Below is the stock chart for the QTrax's holding company. Someone's made a few bucks in what is reminiscent of those pump-and-dump schemes you get in your spam folder.
