Customers of Amazon Prime, its broad perk service, no longer can play on demand most of the songs in the company's catalog. That feature is now limited to customers willing to pay more for Amazon's “Unlimited” music tier. Amazon said the change is part of a major upgrade to its music services.

Amazon Music Prime provides unlimited, ad-free access to on-demand streaming of curated playlists and Stations, plus millions of songs and albums at no additional cost for eligible Amazon Prime members. Eligible Prime memberships include: Amazon Prime membership. 30-day Amazon Prime free trials.

Amazon Music Unlimited is a standalone streaming music service that offers more than 100 million music tracks. Amazon Music Prime, on the other hand, is bundled into your Prime subscription. Music Prime offers the same robust musical catalog as Music Unlimited, but here's the rub: your musical selection is shuffled.

There are many different ways to listen to Amazon Music. Amazon Music provides Prime members with access to 100 million songs ad-free, the largest catalog of ad-free top podcasts, and thousands of playlists and Stations, included with Prime at no additional cost.

Here are some reasons Amazon Music Unlimited titles no longer show as available: The titles were removed from the Amazon Music Unlimited catalog. Your Amazon Music Unlimited subscription expired or was canceled. Your Amazon Music Unlimited subscription was downgraded to Amazon Music Unlimited Single-Device Plan.

Songs keep buffering, pausing, or not playing when trying to stream my Amazon Music. To stream music without issues, you need a strong Internet connection. To troubleshoot streaming issues: Confirm that your device is connected to Wi-Fi or a mobile network.

Having noted some of the key differences, Amazon Music Unlimited looks like the choice for those who are prioritising streaming quality and those who use Alexa devices. However, Spotify's user interface generally works better and is more accessible in our opinion.

Amazon Music Unlimited is the highest level subscription. You don't need Amazon Prime to access it, but you will have to pay a monthly or yearly subscription fee.

Music Library Spotify offers more than 82 million songs and 4.7 million podcasts, which is more than enough to keep most people busy. But Amazon has them beat. Amazon has over 100 million songs in lossless HD quality and millions in Ultra HD. They claim the most extensive catalog of ad-free major podcasts, too.

Amazon wins when it comes to paid plans, because it offers CD-quality music streaming with its Music Unlimited plan memberships. Some of the Music Unlimited songs are even offered in Ultra HD, which is a marked step beyond CD quality.

When it comes to streaming quality, Amazon does seem to take the cake. It offers lossless audio streaming across a lot of its tracks, albums and content, aided by the fact that Amazon Music HD – previously a separate, more expensive tier – is now included with Music Unlimited at no extra cost.

When you attempts to play a song which is only available as shuffle, Amazon Music will select a song similar to the one requested. You can upgrade to Amazon Music Unlimited when a title is not available to play as on-demand. I hope this helps!
