Just listening through them now.
Ain't Nobody - Keys are behind the beat, as are the guitar(s) to a lesser extent, the first guitar being off more than the second.
Mercy - tighter, but the keys are still a little off.
Lady Marmalade - tighter still, didn't like the patches chosen by keyboard.
Master Blaster - Tight, but didn't like the keyboard patches again
Bass and drums locked together well on all the songs.
