Audio only playlists

I utilize my playlist for my music. I have a few hundred songs for my playlist that I get from YouTube music videos. The video takes up my storage space to just for it to play in the background while my phone sits in my pocket. I propose a toggle for downloading audio only or perhaps even a second playlist that is audio only. I am also a photographer and an avid discord meme borrower which leaves me with very little room left on my phone for music on my playlist. This feature would enable me and possibly many others to be more efficient with the limited space that we have.
