Eminem and Adele are both well-known artists, so maybe there's a song collaboration between them? Wait, I don't recall any official collaboration. Maybe they're referring to a mashup or a fan-made track? The title "Angel" could be a reference to something. Eminem has a song called "Lose Yourself" and Adele's "Hello" is popular, but "Angel" might be a different track. Wait, there's a song called "Angel" by Shakira? No, that's "Try Everything". Maybe the user is confused or there's a mistake in the title.
