This tweak enables a hidden setting within the Music app to show all of your TV Shows + Movies. By default, it adds a new library option titled "TV & Movies". Whether you're an Apple TV+ subscriber or not, navigating the TV app can be a pain when you just wan't to be able to watch your purchased library, this turns the Music app into a fully functional alternative. There will also be a noticeable rise in the rate at which the content loads, not sure why, but my guess is that the Music app was built to load content much snappier because of all of the different environments which are nonexistent within the TV app (CarPlay, mediaremote, etc.)
