Amazon has just launched its own music streaming service, but like its line of tablets, Prime Music may take some time to develop.

According to Reuters, Amazon launched its music service Thursday, but cannot boast the kind of library Pandora, Spotify or Beats does. Prime Music is also not a typical subscription service just yet either and is currently being offered free to Amazon Prime customers.

Prime membership was recently upped to $99 for a year's subscription form $79, but it ensures customers free two-day shipping from the official Amazon store. Prime members have other benefits, like the new music streaming service and various free movies and shows on Amazon Instant Video.

The Prime Music catalog will lack any work from Universal Music Group Inc., which includes chart toppers like Kanye West and Lady Gaga.

"If there are a few tracks you want to buy, the cost of doing that in our store will be dramatically less than paying $120 a year for, frankly, a lot of music people don't listen to," Steve Boom, head of Amazon's digital music, told Reuters.

Boom did not go into much detail, but said a vast majority of the 25 million to 30 million songs available on Amazon's digital music market does not sell. The likely culprit is streaming services like Spotify, Pandora and Beats. However, Amazon is in negotiations with Universal to add the largest record label in the world's catalog to the Prime Music service.

Amazon also cannot offer brand new music from some labels and will have to wait six months to add certain songs to its library. Amazon has proven before, especially with its Kindle Fire tablets, that it plays the long game.

Amazon is also expected to unveil its first ever smartphone and the e-commerce website allowed members of the public to request an invite to a launch event in Seattle June 18.
