Mariah said recently that she wants to work with people she's never collaborate with.
Cut JD some slack, his stuff on MIAM was great for the most part (the production on 'OMT' & 'Heavenly' was wack tho). And yeah, none of their songs were WBT pt. 2. 'Triumphant' wasn't either & Memoirs was all The-Dream/Tricky Stewart. Their last attempt at creating a new WBT happened like 8 years ago with 'ISIL', & the closest we got on MIAM was 'YM(E)' which was produced by Rodney Jerkins. AND, even though it's a Christmas album, 'Oh Santa!' & 'Here Comes Santa Claus' were great bops. If they come up with yet another ballad with a beat, that's most likely Mariah's idea.
