Maybe it’s just nostalgia talking, but something about the melody of “Yub Nub” triggers a warm happy response in me that seems totally fitting for the end of the series while the other one just leaves me totally cold.

I could say the same thing in reverse, with Victory Celebration being a lovely tune that fits the end of the series perfectly and Yub Nub doing absolutely nothing for me… so yeah, nostalgia could very well be a factor here, for both of us.
I mean, I’m pretty sure the first version of Jedi I saw was the SE, and for the longest time that was all I knew. So even though I KNOW Yub Nub was the original track, it just doesn’t feel right to me.

I will agree that the transition to the credits is awkward in the SE though. They really should have rerecorded the credits music too, and not just awkwardly cut back to the original recording once the credits started.
