Avalanche - Lyde — 3, I rarely feel any sympathy for electronic music. It's definitely not my thing; it's hard to listen to. But it reminded me of the music from Fashion TV shows, which I watched as a rare novelty on satellite TV as a child.
Gerudo Valley (From _The Legend of Zelda_ Ocarina of Time_) — 6, I've never played Zelda and don't have any particular fondness for it. But of course, I know the soundtrack, and it's generally decent.
Heroes V Town Academy — 7, I like the soundtrack from the fourth game the most when it comes to the magic factions. If that were here, I would have given it a 10. I agree with Alex; the Elven Castle sounds better in the fifth game.
Seiran — 6, interesting associations with a music box, but a bit drawn out.
Touhou Lostword OST - Heavenly Red (Remilia) — 4, something pompous, heroic. It's not entirely bad, but at the same time, it's a bit difficult to listen to (and there are human screams in the beginning and in some parts, music with vocals!!111

).
Ótroðinn — 9, now this is a good track to have on in the background while working. Without any timing cues, I immediately understood where 4:35 was; maybe I'll listen to the full version later, but I'm not sure (and there are also human sighs here!!11

).
Castlevania - Aria of Sorrow - 04.Castle Corridor — 5, I've never played it and I won't. Nevertheless, the sound itself is very old-school; there's something about old soundtracks to 8-bit games. It's as if they put their whole soul into making it sound atmospheric.
Disgaea 7 Vows of the Virtueless - Snow, Moon and Flowers — 6, the fairy-tale flute carries it; the rest is just okay (there's also a fragment with screeching women!!11

).
TNO - Vassal — 5, also very old-school. At first, I had the feeling that I might have heard it somewhere. But in general, 30-40 years ago, this kind of sound was quite fashionable and could be found in various types of music. You could easily hear it not only in some chanson or near-chanson, but also in something more pop.
007_moy_laskovyy_i_nezhnyy_zver_vals — 7, well, this definitely hits the old-school vibes; it's hard not to know it
