When has Mike ever done that?
Destiny, Off The Wall - funk & disco was already out there
Thriller - nothing really new here as far as a sound and Paul McCartney was from the 1960s.
Bad - a lot of acts was doing synth music in the 1980s, since new wave started in the late 1970s
Dangerous - New Jack Swing had been around since the mid-1980s
On some of Madonna's later songs, she would get these underground dance music producers. Mike would get whoever is popular like R. Kelly, Darkchild, Dallas Austin, Teddy Riley, Jimmy Jam & Terry Lewis, Babyface, etc. On Invincible, there was some neo-soul tracks, that had started in the 1990s (Erykah Badu, D'Angelo, Angie Stone, Maxwell). Although they were before neo-soul, you could say some of the songs of acts such as Sade, Anita Baker, & Tony! Toni! Toné! could fit into that. So could 1970s & 1980s R&B ballads called "baby making music", "quiet storm", & "slow jams".
