MTV is expected to announce today that it will partner with RealNetworks, merging the two company's online music services.

This probably means the end of MTV's URGE music site, which probably won't affect much of anyone. As far as we can tell, you could count the number of URGE subscribers on one hand. And you might not need all your fingers.

Anyway, URGE had been a partnership between MTV and Microsoft. But Microsoft has been focusing on its Zune Marketplace since launching its iPod competitor. So it makes sense for MTV to partner up with RealNetworks, the company behind the subscription-based Rhapsody music service.

Whether MTV/Rhapsody will make a dent in Apple's market share remains to be seen. But so far Apple has yet to offer a subscription model for iTunes, so it should be interesting to see if Rhapsody's pay a monthly fee for all the music you want model will gain any traction with MTV's brand name and music library.

Verizon Wireless has also signed on to distribute MTV/RealNetworks content to mobile devices.
