Ah, yes, haven't commented on the music of OoE.
They're good. Some even great, but some others take quite a long time (and game grinding) to get accustomed to. Also, some of the titles of the music looks rather off.... 'Chamber of Ruin' sounds more like 'Festival of Servants' with its rather circus-y style... (although I like the track itself

)
These are the ones I like the most of the whole game:
Malak's Labyrinth: There's some... kind of hypnotic feel with this music, especially in the in-game area with those floating enemies.... a little hypnotic, but this is practically the first tune that gets stuck to my head among the rest

Edge of Sky: It sounds rather melancholic to me

Nice one.
Jaws of Scorched Earth: I believe it's not everyday we hear Castlevania Jazz

Dissonant Courage: Now THAT'S a boss theme

(And OMFG, the rearranged version is just epic)
Also, has someone or can someone pinpoint the composer for each of the tracks? There are two composers, Michiru Yamane and Yasuhiro Ichihashi, and I'm not that good in guessing which is composed by who (my only guess is that 'The Colossus' is composed by Yamane; It sounds a little too similar to some of her previous works).....
