If you are on Windows, going to a playlist and pressing Ctrl+A will allow you to select all the songs in that playlist. From there you can move the songs into the playlist you want to listen to.
You can also make a playlist folder by right-clicking on a playlist and clicking the 'Create Folder' option. From there you can add all your playlists to the folder and simply click on the folder and press Play to listen to songs from all of your selected playlists.
If you have any other questions or you need additional help, please reply 🙂
It's possible to create a playlist folder by going to File > Create Playlist Folder. The playlists will be displayed as a separate playlists on your profile page however. You can find more info about playlist folders on this page.

What I'm looking for is a way to share a playlist in different playlist folder.
I have got the playlist "Rock 70 English". Now I create the following playlist folders "All Rock", "Rock 70" and "All English". Is there a way now to add the mentioned playlist to the three crated playlist folders?
