What is iTunes?
iTunes is the best way to organize and enjoy the music, movies, and TV shows you already have — and shop for the ones you want to get.
You can even tune in to free, on-demand music stations that have been totally revamped by our Apple Music experts.
Enjoy all the entertainment iTunes has to offer on your Mac and PC.
Note: Starting with the release of macOS Catalina, iTunes for macOS will be split into three applications: Apple Music, Apple Podcasts, and Apple TV. Finder will take on the role of managing Apple devices, such as the iPhone and the iPad.
In macOS Catalina or newer, they don't support it anymore. It can still be downloaded for Windows.
