Damn the two of you made this hard. If I were to rank my favourite individual tracks, I think Khan would easily have at least the top five spots, as I'm sure is evidenced by the fact that two songs on her list are in mine too, and a third (Neil Finn's Last One Standing) is in Part IV of Aotearoa: Rugged Individual.
However. Yes, there is a "however". If I did a least favourite tracks list, I think Khan would again have a lock on the top five! While there are more songs I really like or love on Khan's tracklist than LJT's, I find it almost schizophrenic, jumping from songs I adore to songs that would make me commit suicide on the island.
LJT ultimately won my vote because I feel his tracklist provides an incredible listening experience. Those who say "a bad song is a bad song, no matter how good the flow is" are provied to be liars by the first third of LJT's tracklist. There are some songs there that I would never play in isolation, but together, the atmosphere is very rich and I quite enjoyed it. Around about the Daft Punk track, I lose some interest, but by the final third, there are other amazing songs (Muse, Asobi Seksu, Jeff Buckley) and a good sense of flow and atmosphere to keep me going to the end. And the man deserves huge credit for including Pure Reason Revolution's Voices in Winter/Realms of the Divine, one of this competition's very best tracks.
