Why is apple music taking up so much space on my iPhone?

I know this has been posted before a few times but i still haven't found a good answer. With the imazing app, i go to file systems -> iTunes_control -> iTunes -> Artwork and i see two folders, one named cache and one named Originals, i deleted the contents of the cache one and it got rid of a significant amount of data but the Originals folder is up to almost 8gb and it was 7gb a couple of months ago. Does anybody know if its safe to delete the content of this folder too without messing up my apple music?

when i delete the app it goes away, but when i redownload it, it comes back.

My iPhone is up to date and don't have any songs downloaded offline, this has been a problem for me for a year or two now.

I saw someone here say it happens if you have a large library and listen to music a lot, both of which apply to me, so im starting to wonder if this is just a problem i gotta put up with.

edit: I don't know why it says iPhone 5c, its an iPhone 11 pro
