Thank you very much!
I don't have much to say about every one of them, so I will pick mostly my favourite ones.
Some of them are so similiar to the first OST's ones, I thought they just copied them.
03. Pride
Track is kind of boring at the beginning, but it sends chills down my spine, when the music crescends at the end.
04. Envy Revealed
Very nice and dramatic.
05. The Plot Thickens
Mentioned similiarity. This one is like lacking "Clash of Alchemists"
09. Desolation
Again, "Lapis Philosophorum", anyone?
Though, I like it anyway, it seems "remixed"10. The Fullmetal Alchemist~Legato~
Main theme instrumental. Kind of nice.
11. Nocturne of Amestris~Duet~
Sends me to sleep. Peaceful~
12. Daylight in Amestris
Wow, I don't think I've heard this one yet. Maybe will be played at the end : x I love it.
13. Nocturne of Amestris
Like this one as well. (It is different than the ~Duet~ one.) It has nice atmosphere.
15. T.B.C.
Again, simply "Laws of Alchemy" ripoff...
20. The Land of Ishvala
Fits. But wasn't it used when
Ranfan reappeared?
24. Versus Homunculus
Woah, gets my blood boiling. And original! *le gasp*
25. Battle Scherzo
Ohh, Mustang vs. Lust's and 26th episode's one! One of my favourites. I approve.
26. Far East Suite~Pizzicato~
Oh. I like it as much as the original. Reminds me of Ling's nature, lol. So playful.
27. Pastorale Rondo
Nina's episode one

Took it long enough. I like it very much.
31. Brotherhood~Postlude~
Hm, I think I've heard this one before. It's beautiful, but I was hoping for something new...
Apart from being slighly unoriginal, it has its awesome pieces.
