Elton John, "Madman across the Water"
Justin Timberlake, "What Goes Around"
I'd say this is one of the more subtle ripoffs, but the more I listen, the more I hear it. Elton is worthy of ripping off, and Justin made a better choice than what you'd expect from the Mouseketeer. But all in all, I still think music might be the weakest of Justin's talents. I just don't get the music from him. He's funny. He can dance. And he's got that charisma that just makes people forgive him for whatever shlock he puts on a record . . . as opposed to Sir Elton who gets away with everything about himself because his music is that good.
Anyway, check out the ripoff and see what you think.
