Where did all my music on Apple Music go?

i used to use Apple music on my phone and ended up canceling my subscription for a couple years. now my man has me on his family plan but all of my music disappeared except like ten songs i downloaded. where did my music go? I didn’t have a laptop, I’m talking about all the music I had added to my library in Apple Music, not iTunes. I had an iPad that got stolen, so I replaced it. I’m using the same iCloud i.d, so now that I’m using Apple Music again why doesn’t my music library show anything? It shows all of the different playlists I had, but none of the music that went into the playlists.
