Not generally one to post feedback but this seems like a UX/UI error that should be addressed.
When I open an album and select "..." next to any song on that album, the first few options include "Hide Song" and "Remove From This Playlist" if that song is within a playlist. I recommend moving those down a few options to prevent users from inadvertently deleting or hiding a song they actually intended to share or add to a playlist.
I made this error and had to scour the internet using only my memory of the album art and the first word of the song title (which was in Portuguese) to recover a song I accidentally removed from a playlist.
