My Question or Issue

Hi, I have an android phone and premium subscription. I added a whole album of music to a playlist by mistake, and now would like to transfer( delete) from that playlist to a new one. I know I can add a song to many playlists..but then how do I delete it? I must be missing something obvious?! 

Thanks!
