How do I print an Apple Music playlist?
Quick answer
On a Mac, select the playlist in the Music app and press Command-P. Apple's own guide describes picking CD jewel case insert in that print window, which prints the playlist's songs as a list.
Before printing, sort the playlist the way you want it on paper, since the printout follows what's on screen. If you'd rather have a file than paper, open the PDF menu at the bottom of the macOS print window and choose Save as PDF.
The jewel case layout is small and built for a CD case. For a full page you can format yourself, export the playlist instead: choose File > Library > Export Playlist, save it as a text file, then open it in Excel, Numbers or Google Sheets. Apple says that file includes all the info from each song's Info window, so hide the columns you don't need, then print.
The Music app on iPhone and iPad has no print option. Your best bet is a web tool that turns the playlist into a file, then printing that file from your phone or computer. Our page on exporting a playlist as a text file covers both routes.
