Google fired a shot over the bow aimed Squarely at Apple and Amazon today, when it announced a free music-matching locker service. The improved Google Play service, which launched in Europe one month ago and is now available in the US, replaces the Google Music which debuted in beta in 2011. The service scans a computer’s music collection, and then compares that to content stored on Google’s servers to avoid uploading duplicates. Users can then stream and listen to their entire music collection from the cloud. Google’s offering also offers the highest bitrate of any of the competing services, 320kbps compared to 256kbps.
