I think a lot of it sounds like Michael and the song doesn't sound like a normal Janet song LOL Why all of a sudden would she be singing about the truth?? It seems like maybe Michael got his voice disguised a bit but not too much where us fans can still hear him. Even in the lyrics part where it says Trust in me I feel thats MJ's way of telling us to trust in him that we should know by now he wouldn't do what the media says he's done and did like being a drug addict. Come on, if was a vegetarian and was careful about what he put in his body he for sure would not use heavy duty drugs.
And the line about we need to cherish each like it's the last and I was asking myself where have we heard this similar line from?? The song Jam "we must live each day like it's the last"
I believe Michael wrote that song and secretly sang with his sister.
