Why does my Apple Music take up so much storage and how do I reduce it without losing my songs

Back at it again with the questions

My Apple Music takes up almost 3GB of storage and I just want to know if there’s a way to reduce that number without deleting the app? Is there’s a way to check downloads even if my device says download (this causes all my songs to download and I don’t want that) Please this is an ongoing issue and the reason for my past issue that has negatively impacted me in some way.
