Amazon.com said it will increase the number of songs available to Prime members without advertising from two million to more than 100 million. It also plans to offer more ad-free podcasts. “Prime members can discover more new music and podcasts based on their likes; shuffle play any artist, album, or playlist in the catalog; stream a collection of All-Access playlists tailored to personalized listening preferences on demand and download them for offline listening,” the company said in a blog post.
