Can we talk about the logh soundtrack ?

I discovered LoGH very recently (I've been watching the OVA since December, I'm currently at ep 91), and I've just rediscovered classical music as a whole. I now have a bunch of musics in my playlist (and I can't help but remember the most impressive scenes related to them). My favorite is Mahler Symphony No. 1 - Stürmisch bewegt - Energisch What's yours ?
