Less than two months after its launch, Amazon is adding hundreds of thousands of songs to Prime Music, its streaming service. Prime Music launched in June with over a million songs, but it was missing many consequential artists and albums.

Amazon is adding new artists, along with tracks from existing artists to Prime Music. Artists including Neil Young, Ella Fitzgerald, Al Green, Miles Davis, Ray Charles, Kendrick Lamar, Linkin Park, Shakira, Edward Sharpe & The Magnetic Zeros, Young the Giant, A$AP Rocky, Elvis, Oasis, Kacey Musgraves, David Guetta, Deadmau5, and Skrillex will be added to the Prime Music catalog.

Amazon is also adding hundreds of new curated playlists, which it calls "Prime Playlists," to the fold.

The initial lack of songs hasn't hurt Prime Music, according to Steve Boom, Amazon's VP of Digital Music, who said, “the response we’ve had to Prime Music has far exceeded our expectations." Prime Music comes free with your Amazon Prime subscription.
