There's only two ways. Apple Music (streaming) and iTunes Store.
iTunes Match lets you "upload" your library to Apple. It matches your library against Apple's catalog. If they have the song, you get a copy of their version of the song. If it doesn't have a match, they retain your uploaded file.
I have a lot of random local music that isn't on iTunes, and which you can't easily find anymore. For years, I was paranoid about losing my ripped copies of the files, but iTunes Match has preserved them for me, in the cloud, for years now.
One of which gives you re-downloadable DRM-free files.
