Last week it was reported that Amazon had inked licensing deals for its cloud storage service with two of the four major labels. Now CNet reports that all four of the major labels have signed on with Amazon, paving the way for an upgraded cloud music service some time next month.

According to CNet's sources, Amazon could debut new features for its cloud music service some time in July. One source says Amazon could offer the ability to scan users' music libraries and match the songs, a service iTunes already includes. Currently Amazon cloud users have to upload each of their songs individually into the cloud, rather than Amazon recognizing the tracks and offering the same songs from their own servers.
