Adding entirely new Music?

[Xehanort88]

So, I've been digging a bit in the music files, it works somewhat similarly to XCOM2, but in Unity rather than Unreal Engine 3. I still am not sure how looping works, however, or how feasible this is. I think it could be possible at least to add the files, but the purpose of new music would be in new adventures or expanding the campaign.
