Hey, we dont know about ost nothing for now but here is my suggestion. C1 and C2 music were diffrent, its obvioius ofc becasue there were set in diffrent locations. C1 music was great and it suit to a jungle environment and some time it was similar to some tribals music. C2 was set in city and there were more eletronic tracks, that ones were also great and t suit to urban environment more. If C3 is combination of C1 and C2 so it would be great if the music would also be a combination of instruments from C1 (fluetes, drums, violoncello) and C2 music wchich like I say were more modern.
Here are some music wchich i like from C1 and C2:
