There were a ton of files, so it was somewhat challenging to mix them all into a decent track compared to other locations. And Colombia is going to be even worse in that regard. Some parts felt unfamiliar thus I put them in the "Marketplace" and "Streets of the Slums" sections, there might need to be additional labels/timestamps in there.
By the way Mumbai's music is the most location fitting and diverse soundtrack in the entire game I'd say.
