When we last checked in, Amazon was thought to finally be pushing for full music rights in its Cloud Drive and Cloud Player services. It might be a smooth operator at the negotiating table: subsequent tips to CNET maintain that the top four major labels (a currently-independent EMI as well as Sony, Universal and Warner) have all signed deals that will let Amazon offer the same scan-and-match music downloads and streaming as Apple's iTunes Match. The pacts would let Amazon offer access to every song a listener owns without having to directly upload each track that wasn't bought directly from Amazon MP3. Aside from closing a conspicuous gap, the deal could end a whole lot of acrimony from labels who were upset that Amazon preferred a free-but-limited service over having to charge anything. The online shop hasn't said anything official yet (if at all), but any signatures on the dotted line will leave Google Music as the odd man out.
