Create a playlist in Music on Mac
You can create playlists to suit specific moods, to organize songs with a certain theme, or to group songs you want to burn to a CD.
Playlists you create have this icon 
next to them.
Ask Siri. Say something like: “Play the R&B playlist.” Learn more about Siri.
You can also create a Smart Playlist that updates automatically based on rules you choose, or create a Genius Playlist that includes music in your library that’s similar to the selected song.
