Shazam Lets You Buy Music in Google Music
Shazam has rolled out an update to their app for Android that has an interesting tie to Google Play Music. With this update, when you are having the app listen to the music that is playing around you, it will provide you a link to purchase that song from within Google Play Music. This complements the ability the app already has to buy music through Amazon Music and other services but it appears now that Google is the path they want you to go.
