Google Play Music adds library matching in U.S.

When Google launched its Play Music service in Europe , it included a feature that scans a user's library and automatically adds high-quality versions of songs the company has on its servers. Matching songs is now a feature available to Play Music users in the U.S. Rather than upload 20,000 songs, Google will add existing files to a user's library and only upload songs it does not already have on its servers. Over the next few weeks, Google will apply the match strategy to existing libraries and replace lower-quality songs with 320kbps MP3 files when available.
