Chrono Cross
Best Song Standalone: Uh. Sure, Dream of the Shore of Another World. Hard to pick between that & Radical Dreamers, Unstolen Jewel.
Worst Song Standalone: The Splendily Surprising Grand Magic Troupe. Bleh.
Best Song In Context (ie, song used the best in-game): Sure "Prisoners of Fate/People Seized with Life/etc." I rather liked the context use of the special Chrono Cross song in Life A Distant Promise, too.
Worst Song In Context: Gale. I'm not on the total Gale hate-train - it'd be okay as a random piece on the soundtrack - just not the most played one.
Overall Impression of OST: At one point I'd be tempted to have made Chrono Cross my favorite soundtrack of all time. I've cooled on that some since, but there's no denying that this is a soundtrack with multiple (!) 10/10 tracks when most soundtracks struggle to have just 1. And even when the soundtrack is more blah / subdued, it fits the entire mood of the game like a glove. So... how much is it worth punishing the soundtrack for some filler town/dungeon pieces? Not much, IMHO. I just created a slightly shorter version of the CC soundtrack, and bam. Aside from the 3 tracks mentioned above as worthy of calling out, there's also Scars Left By Time, Star Stealing Girl, Time of the Dreamwatch, Forest of Illusion, Boss theme, Chronomantic, Burning Orphange, and various others.
Final Rating: 8.5/10
(I don't normally give .5s, but CC is a 9-10 for stand-alone listening, but a ~7-8 in-game depending on how much the worse tracks are held against it, and that's a notable split.)
