Previously, Amazon has offered an MP3 store where customers can buy music using a Web browser or the MP3 app for Android, which now includes the Cloud Player functionality.
That means Google, Apple and Amazon may just be vying for many of the same customers.
"Interestingly, both Google and Amazon target the Android device as their player of choice, which in a way does encourage greater competition between Android and iOS in terms of offering customers with a rich music experience on both devices," said Shimmin.
Shimmin said Google has a good shot at making a go of a music service if it's able to build a strong record label ecosystem.
"I don't think this can turn into a losing proposition for Google," he added. "I think it's an important move to further secure and bolster Android's popularity as a mobile device capable of matching Apple's iOS blow for blow."
