Currently, Siri can play music from different apps, but users have to clearly specify the apps after the song (for instance, 'Play Fix You on YouTube Music). 'Afterwards, it used my selection by default, without specifying 'on Deezer' each time, despite it being a third-party app,' the user added. The user with the iPhone XR smartphone explains that while asking Siri to play a song, the Apple voice assistant is inquiring about the specific music streaming platform. The Reddit users (u/matejamm1) spotted the option to change the default music app on the iOS 14.5 public beta 1 that was rolled out last week.
