That When You Believe song was very textbook 90s Babyface balladry, nothing innovative nor remarkably special about it other than the two women that sang it.
But I guess this thread is supposed to be yet another thread to excessively talk about how Rihanna can't sing & ****, so whatever.
The difference is that When You Believe(ok song) was an actual duet, it was meant to be a duet , while S&M (great song) remix was a cheap strategy to get #1
For the most part, it never has been. There's always your wonderful exceptions, though. Don't fool yourself into thinking any era is completely or even mostly innocent.
