For me, it could be the intro to Take the Time. It's my favorite Kevin melody, love the funky bass and drums, the samples are cool, JLB is so energy, powa, the lyrics are motivating; I think it's time for a CHAAAAAAANGE, then the organ cuts trough underneath it...great stuff!
Other noteworthy candidates would be the UAGM chorus and the LTL bass outro.
On a side note, the ending of Metropolis on Score is something magical, with James' expressions, Mike throwing out the drumstick. I probably watched that part hundreds of times.
