...it's the same song. He sounds great though.
You're saying that the chocolate ice cream is made by Haagen-Dazs and not Ben 'n' Jerry's. It's still chocolate ice cream. You know, if ice cream had gang vocals.
Actually, if you wanna use that analogy, the brand is actually the band each with their own version of the song (ice cream), a cover of the original (neither created chocolate ice cream, but it's a very popular flavor (song) like Ring of Fire that gets covered constantly). A new vocalist would be like a new or different ingredient, changing the taste/sound into something sorta new. If that makes sense.
