With how "slow" the opening is and how thematically different it is from the drop, I almost wish the two were a little more directly integrated, because while they're both interesting, it does feel a bit jarring to not only have it flip on its head halfway through, but to not include the original synth bell-esque segment of the first part in the second one. Again, regarding the speed, getting to hear the melody with the string pad kick in is nice, but with how relatively short the track is, it almost feels like it takes a bit too long getting there. It's a neat take on the source track, though - it's not really something I'd expect to be done with it tonally. Is the clavinet bass thing in the second part using an arp at all for the melody, or is it completely custom?
Link (can be streamed or downloaded) For those not aware, Sinjoh Ruins itself is already a medley of several tracks from Pokémon Diamond, Pearl, and Platinum for the DS. Both Sinjoh Ruins and its main source, Mt. Coronet, are unusually quick and complicated for Pokemon area music (only really rivaled by some of the important battle themes, i.e. Giratina's), while this remix looks to expand on segments that don't get as much presence as they could have (the second half of Mt. Coronet, Giratina's theme, etc.) and also adds in some new stuff (Arceus, Distortion World). There's also the Pokéathlon Finals theme in there as a liquid DnB-esque segment to pick up the pace and conversely provide some levity before the bombastic stuff at the end.
