Amazon has announced a much needed expansion of its Prime Music catalog by “Hundreds of Thousands” of songs.

When Amazon Prime Music was launched last month, it entered an extremely competitive market.

With a meager one million song catalog, it paled in comparison to established players such as Spotify and Rhapsody, which boast around 20 million and 30 million songs, respectively.

But in Amazon’s usual slow and methodical fashion, it is taking steps to become more competitive.

In its first expansion since release, Prime Music will offer many additional songs from artists already hosted by the service.

In addition, many artists will be making their Prime debut. These include notable names such as: John Coltrane, Young the Giant, Skrillex, Wyclef Jean, Shakira, Al Green, Oasis, Elvis, Ray Charles, Miles Davis, and many more.

It’s true that even with this expansion, Prime Music still has a way to go to in becoming a viable alternative to Spotify or Rhapsody. But if the slow, steady, and successful expansion of Prime Instant Video is used as a tool of measure, expect Prime Music to close that gap as time progresses.

Amazon Prime Music is a free service to Amazon Prime Members.  It can be accessed on the Kindle Fire (2nd Gen), HD and HDX, the iPad, iPhone, and iPod touch, on Android devices (v.4.0 and up), PCs, Macs and through Amazon’s website.

Amazon offers a free one month trial of Amazon Prime to new subscribers. After the free trial, Amazon Prime costs $99 year.

Amazon Prime Membership also includes free two-day shipping with purchase of many of Amazon’s products, instant streaming of 40,000+ movies and TV episodes through Prime Instant Video, and free borrowing of over a half million books through the Kindle Owners’ Lending Library.

Will the expansion of Prime Music be a deciding factor in buying an Amazon Prime membership?
