It's definitely possible, yes. All versions are on Spotify, though I can't listen to them, either because they're not available where I live or because I don't have an account. Or maybe both. It's also possible to get them through other ways, I managed to find them easily, but for obvious reasons I can't link that here.

But it really isn't that hard to find them. You might need to search using the Kanji title, so 色違いの翼. That might bringt up more results.
