And it's called
Qtrax. It's Windows only, for now - OS X support is coming in March. 25 million tracks, with EMI, Universal, and Warner on board. No track limits, no "subscription" service, but tracks do contain DRM. Ad-supported, and supposedly the ads are not intrusive (they don't come up every time you play a song, for instance).
Windows beta available for download at midnight, EST. OS X client available on March 18, with some kind of "iPod solution" to be announced in April.
A step in the right direction, certainly...though I'm waiting to see how they handle this on OS X in a couple months.
(This is the correct thread, please don't delete me! I hit "Submit", the connection hung; I hit the stop button, refreshed the forum in another window, the thread didn't show up, so I tried again. Somehow it ended up getting submitted
thrice instead of twice; not sure how that happened. At least it didn't
ban me this time.)
