Discussion
Apple discourages using this method in iOS 15, tvOS 15, macOS 12, and watchOS 8 or later. Load tracks asynchronously using loadTracks(withMediaCharacteristic:completionHandler:) instead.
You can call this method without blocking the current thread when the data in the tracks property is already loaded.
