Hi! I'm so glad you asked!
Currently, there is no definite way you can transfer music or playlists from one account to another.
However, there are some tricks that ultimately accomplish the same goal.
On your old account, you can share your playlist with your new account, so you will be able to access all your old favorite songs.
But, if you make your playlist collaborative, your new account will be able to edit and add new songs to the playlist.
Making your playlist collaborative would be essentially transferring your music from one account to another.
I hope this was helpful! Let me know how it goes!
