For a while, you could only get your legal music from three main music distributors: Napster, Real Rhapsody, URGE, and Yahoo. However, there have been a lot of changes. With restriction-free music gaining momentum, with distributors like Wal-Mart providing cheaper music, and distributors like Amazon simply offering more music, business is awful hard to come by for any of those distributors. Yahoo, which at one point offered more than two million songs, has been forced to shut down the Unlimited music service. Yahoo has officially sold the Unlimited music service to Real Rhapsody, and current subscribers of Yahoo will be given a migration notice very soon, if they haven't been already. Yahoo will still be in the music business, though, and is considering offering a very limited catalog of subsidized free music, much like competitor Spiral Frog.
