Amazon today announced unlimited storage for music in its cloud drive. The catch is you have to upgrade your overall Cloud storage (also includes Docs, Pictures, movies, etc) to the 20GB plan which is $20 per year. Once you do that, you can upload “Unlimited” amounts of music and play it anywhere. So, this appears to be taking on Spotify, Google and Apple’s iTunes Match (though each service is slightly different).
Speaking of Apple, the Amazon Cloud web experience is now also optimized for the iPad. Full press release below:
