Apple has clarified that the iOS 14.5 beta is not actually allowing users to select a new default music service, as has been reported. Following the beta's release back in February, a number of beta testers noticed that Siri would now ask which music service they would like to use when they asked Siri to play music. Instead, the feature is Siri intelligence-based, meaning it can improve and even change over time as Siri learns to better understand your listening habits.
