Both are quite good for mobilization, or even battle music. Thank you John, they'll be a worthy addition to the East christians. I can say with certainty that the inclusion of music really makes a difference in the atmosphere. The addition for the Turkomans really gave a cinematic experience with them.
Also, thanks to Mirage's work, we now have managed to dispel what had been a real hindrance in cultures - We should be able to have a separate East Islam and West Islam music, along with West Christian and East Christian. Both will blend somewhat, but particularly in Campaign music they will retain their own quality. We should be able to get an Indian music set too, I'm just not 100% sure about it right now. East Islam will be covering the Kipchaqs. It's not great but there's no real point to a steppe culture (No buildings suitable for them) music set, since there will be only a handful of provinces which are steppe, and thus have steppe music in their battles. I wish that the game set battle music based on faction, rather than the culture of the territory, but I can see the logic in it, it sadly keeps us from having great Mongolian music when facing the Mongols.
