I'd love an expansion of RealTracks and RealDrums for all different styles of funk from your traditional James Brown stuff, to psychadelic '70s disco stuff like Parliament or Sly & The Family Stone, to Prince. MIDI just doesn't quite cut it when trying to emulate, for example, slap bass. So, in the words of Parliament, "Weeeee want the funk! Give up the funk! Ah, weee need the funk! Gotta have that funk!"
