Ken Yanagimoto - Sky Ruin
I've not been particularly fond of this piece in the past, but I was surprised by what a difference a few remixes made to my perception. This one in particular completely reinterpreted the tone for me, and as such is an excellent example of what is to be gained from seeking out arrangements sometimes.
Sharp Eight - nice middle with bad girl
Traditional Old Man & Stylish Girl represents missed opportunity to me; I don't appreciate its intro (it doesn't go anywhere), I've never been impressed with its carrying lines (ditto), and the "chorus" seems flipped from what it ought to be (why are the best parts in the background?). To clarify, these are subjective objections; so for this feature, I was determined to find something that presented the motifs in a way that satisfied me personally, in hopes I could overcome my prejudice against the piece. I'm not sure this is it, as it doesn't quite rely enough on those motifs, but it's going in the right direction.
TaNaBaTa - Golden Route
Opposite end of the perception spectrum, Interdimensional Voyage is one of my favorite stage themes in the entire series. As such, my prerogative was different; find an arrangement that was particularly unlike the original, while still holding to the motifs. This seemed suitable enough for the feature, contrasting well without being overbearing. Couldn't find the transcribed lyrics, though . . .
