Least Favorites: Tower Of The Shadow Of Death (because overplayed af), Palace Of Solomon (same reason), To Make It To The End Of Battle (I think it's a mixing problem... the drums sound terrible and ruin the piece)
Most Favorites: Holders Of Power (dumb name but cool track), Final Battle (it helps that The Last Moment Of The Dark precedes this in-game, setting up a good emotional reaction), Palace (somber and lonely, like my life), Ruins Of Moondoria (dat solo tho)
A Still Time and Don't Go So Smoothly! are annoying but I wouldn't put them in my list of least favorites. Campanile Of Lane and Noble District Of Toal are cool but I wouldn't put them in my list of most favorites.
You & I have some similar opinions of the Turbo Ys 1 & 2 soundtrack.
This version of Palace of Solomon(PC/PSP) made me appreciate the song MUCH more
The Dawn of Ys version of Tower of the Shadow of Death helped me warm up the that song more, along with this version:
I do really like To Make the End of Battle, but this versions kills it, gives me friggin' goosebumps, especially at 1:16. Holy hell does it hit my emotions!
Some of my other favorite tracks in general from the Chronicles version:
Tender People
Dreaming(missing from the Turbob edition sadly)
Also, his version of Termination from Ys Origin is goosebump city for me!
