Sorry to disappoint, but Qtrax is falling just a bit short of its promised 25 million tracks at launch. Qtrax busted out its software in "beta" this evening, but isn't offering a single song -- or even a working music browser. The application is a barely skinned version of the open source Mozilla-based Songbird music player, which has certainly come a long ways since its infancy, and which means Qtrax has done just about nothing for you yet -- other than lie about label deals. When you launch the application it helpfully points you to a placeholder page from a Oracle application server, and that's all you'll be getting until Qtrax manages to get label deals sorted, which isn't looking likely at this point.
Update: 4 hours later and we can see music. About 10 million tracks by their count. However, clicking download results in an error message, "Downloads coming soon!!" How soon, exactly? Would that be after the contracts are signed?
[Thanks to everyone who sent this in]
