Having to re-download my music EVERY DAY

I have scrolled through everyone’s frustrations & related chats, but haven’t been able to find a solution. I went into SETTINGS & followed one user’s instructions to make sure iCloud music was on, etc & I had zero luck in solving my problem. My music stays downloaded for a day @ best, & every night I have to re-download all of my music! Any help would be much appreciated, it’s an annoying pain in the ***.

Thanks!
