When Duran Duran became a trio by the 90's the for sure went more dance. in 1993 when they had their resurgence with come undone and ordinary world, I think those were very dance oriented songs.
I cant speak to PSB, not saying they didnt go more electric, which is not my taste, but to say Duran Duran didnt go more dance I think is false, they even had comercial success with their more dance type music, This doesnt include Biggies' sampling of Notorious in the 90's which was straight fire imo, but i am a huge Biggie fan, through in some classic Duran Duran and i was hooked from the get go, lol.
