When did cover songs become annoying marketing ploys?
LOS ANGELES (AP) -- There are about 600 versions of Adele's Oscar-winning song "Skyfall" on the Spotify subscription music service. Not one of them features Adele.
Adele's label, XL Recordings, keeps her music off of all-you-can-listen subscription plans until download sales peter out. In the meantime, copycat artists fill the void, racking up royalty revenue, often before customers realize they've been listening to someone else.
