Given the rise in streaming music services like Spotify, the traditional digital sales model is dying a slow death, and there's no question that Apple's iTunes has not only been a linchpin of the digital music world during the past decade, but still remains the most popular online retailer of songs and albums. The Cupertino's iTunes Radio streamer hasn't really hit the heights in its short lifespan, and recognizing that it may lose ground on the rest of the field if it doesn't adapt to the current market, it's looking probable that the newly-acquired Beats Music service may be integrated into iTunes.
