How do I play my iTunes purchases and all of my other Apple store content on an Android phone?

How do I play my iTunes purchases and all of my other Apple store content on an Android phone? My Dad gave me a Galaxy S10 and I signed into Apple Music, but I can't see anything from my library. I don't have an Apple Music subscription, I just want to be able to use everything I've already bought, and keep buying music through the iTunes Store.
