It looks like the rumors were true: Amazon has just launched Amazon Prime Music with a million-plus songs and unlimited streaming with no ads or restrictions. As we noted earlier, the service is free to Prime members (only in the US for now) who've paid $79 to $119 for a subscription, and Amazon clearly hopes that it'll be yet another carrot to lure new subscribers. You'll also be able to download music to listen offline, which will be available on Kindle Fire, iOS, Android and Mac/PC devices anywhere, thanks to Amazon's Cloud Player -- now known as Amazon Music. The site has already been stocked with hundreds of "expertly programmed" playlists like "Powerful Women of Pop" and we were able to successfully sign up and start listening ourselves. Note that while a million songs sounds like a lot, Spotify currently has 20 million songs and Deezer has 30 million. In addition, the site doesn't seem to carry much new music yet, with quite a few songs in the Billboard Top 100 missing. Still, given other Prime perks like free shipping, streaming and the lending library, it might be enough.
