Following the footsteps of Apple Computer’s iPod/iTunes stratagem and to provide an end-to-end digital music solution, CD retailer Best Buy is partnering RealNetworks, an established brand in the digital space. Rhapsody 4.0, the latest version of Real’s digital music service will be used as the engine by the Best Buy and the store will be co-branded. According to the pact Best Buy will retail the Sansa e200R, a Rhapsody-branded MP3 player from SanDisk, which comes in a 2GB model for $139.99 and an 8GB model for $249 by October 15. SanDisk player shoppers are likely to get a free two-month trial subscription. With lots of alliances rising and breaking, it would be interesting to see how long the partnership advance.
