Shazam users have spotted something on their iOS apps: a Listen Now feature with Apple-owned Beats Music. Much like what Shazam lets you do with iTunes Radio, Rdio, and the like, you can tag a song on the app and it can instantly play that on Beats Music. The catch is you would need to have a Beats Music subscription or are availing the 14-day free trial of the service. You also need to have the latest version of Shazam installed.
