Intro to playlists in Music on Mac
A playlist is a custom compilation of songs and music 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 iPhone, iPad, or iPod touch.
Burn a CD of songs.
Organize your music library.
There are four kinds of playlists; you create the first kind yourself and Music creates the others for you.
Standard playlists: You create these playlists by dragging items to them.
Genius Shuffle: Music chooses a song, then plays songs that go great with it.
Tip: When you join Apple Music, you can add playlists created by any Apple Music contributor to your music library.
Changes you make to your music library (creating playlists, for example) are updated across all your devices when Sync Library is turned on in General preferences. If you’re not an Apple Music subscriber, the changes appear in your library the next time you sync your device with Music on your computer.
