Intro to playlists in iTunes on PC
A playlist is a custom compilation of songs and videos. You might want to create a playlist to do the following:
Suit a specific mood or occasion. For example, you could create a playlist for a dinner party, a wedding, or your morning workout.
Select certain songs to share with others on your local network or to sync with your iOS or iPadOS device.
Burn a CD of songs.
Organize your iTunes library.
Note: You can create playlists for any media type, not just music.
There are five kinds of playlists; you create the first kind yourself and iTunes creates the other four for you.
Standard playlists: You create these playlists by dragging items to them.
Smart Playlists: Specify some rules for iTunes to follow, and it creates a Smart Playlist that updates automatically as your library changes.
Genius Shuffle: iTunes chooses a song, then plays songs that go great with it.
Genius Playlists: Select a song in your library, and iTunes creates a Genius Playlist of similar music in your library.
Genius Mixes: iTunes creates an ongoing playlist in a particular genre—like a commercial-free radio station—using the songs in your library.
Changes you make to your music library are updated across all your devices when iCloud Music Library is turned on in General preferences. If you’re not an Apple Music subscriber, the changes appear in your music library the next time you sync your device with iTunes on your computer.
Also, when you join Apple Music, you can subscribe to playlists created by any Apple Music contributor.
