Search engine giant and Android maker Google is joining the crowd of online music stores soon.

A report from the New York Times said Google is negotiating for song licenses with record labels to start the ball rolling for its still unnamed MP3 store and start eating up Amazon MP3's and Apple iTunes' market share.

The MP3 and iTunes have the widest collections of songs with 17 million and 14 million songs, respectively. iTunes sold its 10th billion song in February last year.

According to the news citing unnamed sources, the Google music store will complement its Music Beta cloud music service launched in May. The Music Beta, however, is not supported by licensing deals with record labels just like Amazon's Cloud Drive.

Negotiations for licensing agreements have been protracted as record labels are wary of getting their songs pirated. This gives iTunes the upper hand for having its entire collection licensed.

There are about 45 online music stores with varying number of songs in their catalogues and area of sales. Those offering more than 10 million songs include 7digital, Artistxite, Napster, Rhapsody and Spotify.
