You might be thinking, doesn’t Google Play Music already stream my own music back to me? Yes it does but now it does it in a way that has a few hidden bonuses. Not only does matching the music in your collection with music in Google’s library mean all of your music will be played back at 320 kbps, it also eliminates the need for the long upload process. As a guy who still has tracks ripped at 128 kbps, this makes me very happy.
Google launched Play Music, including the music match feature, last month in Europe. The free service has a 20,000 song max. If that’s not enough music for you, check out our guide to the best music streaming options out there.
