Amazon.com, Inc. (NASDAQ:AMZN) is up next on our list of the best music streaming service right now. It launched Amazon Prime Music in 2014 and so far it doesn’t seem to have caught on in comparison with Spotify or Apple Music. Edison Research estimated that 51% of people in the US are familiar with the brand, but only 6% listened to it. This is interesting since Amazon also has over 63 million Prime subscribers, which can enjoy some benefits from using Amazon Prime Music, the main of which is that the service is free for them. However, there’s a catch: there are just around 2.0 million songs available, which may sound like a lot, but is significantly lower than compared to Spotify’s 30 million-song database. To address this issue, Amazon.com, Inc. (NASDAQ:AMZN) launched Amazon Music Unlimited, which is more similar to Spotify and Apple Music in terms of both costs and content availability. The new service is available for non-Prime members at the same $9.99 per month that other companies are charging. Then there are two plans for Prime subscribers. One costs $3.99, which is extremely cheap, but is available only on Amazon’s Echo (or Dot or Tap) speakers. The other costs $7.99 per month, which is close to the money charged by Spotify, but the savings can be added up over time (and spent on cool stuff from Amazon).
