It’s hard to find out what song was just playing on Beats 1 when you’re not inside the Apple Music app. Though Apple has no solution for this minor missing feature at the moment, you can still get live updates of the tracks playing on Beats 1.
Thanks to an Australian Developer, Callum Jones, who’s currently in San Francisco. Callum Jones created an unofficial twitter account that live tweets what’s playing on Beats 1. You can follow the account at @Beats1Plays.
