Remember the Rhapsody e200 Sansa as set up when new? It had a large collection of Channels preloaded. You have a cool idea there, reserving the internal memory for recordings and channels, and using the external memory for everything else, one could have a very nice assortment of new music to browse.
The Channels tracks are managed differently than other music, as a unique playlist that is automatically updated using the Rhapsody client.
