>Anyway, I think you overstate the difference a bit; they obviously sound different but they are both killer tunes...

Luv N Haight is one of the most advanced funk songs ever. Stand is a simple pop song. Stand has a funky coda/ending but that doesn't make it a two part song. Lot's of 60's/70's songs had a different sounding endings than the rest of the song - just a flourish or whatever. Doesn't make them 2 part songs.

The ending of "Luv n haight" shares the same music as earlier parts of "Luv n haight" so the ending isn't a complete new thing like the ending of "Stand" is completely new to "stand". So I wouldn't say "Luv n haight" is a two part song either.
