Playing music in the background while using YouTube Music has so far been possible all the time, but this option was reserved for people who pay a YouTube Premium subscription. Otherwise, the application did not allow background music to play. However, this state of affairs is changing, as YouTube itself boasted on its official website. We can officially say that playing music in the background via YouTube Music will be available to all users, including customers using the application for free.
The new option will be available to all users from 3rd of November this year. Initially, the function is intended only for customers from Canada. However, it is worth remembering that while using the free plan for YouTube Music, advertisements will also be played from time to time in the background music mode. To get rid of them you will need to purchase a Premium plan.
