Google updated its Google Music service on Tuesday with a “music matching feature” that is sure to make streaming music from the cloud more convenient. Google Music can now scan your entire library of music from your computer and match up to 20,000 songs in your cloud library so that there’s no need to upload songs anymore. Matched music will be streamed at 320 kbps and won’t cost a single penny, unlike Apple’s $25 iTunes Match service which streams music at 256 kbps AAC and Amazon’s $25 Cloud Player which streams at 256 kbps MP3. Google Music’s new song matching feature is Android-only for now, as the service isn’t available on any other mobile platform. Read the full story at Boy Genius Report.
