Would be nice if we could fetch Audio, Translations & Commentaries from https://www.gitasupersite.iitk.ac.in/ which is a nice reliable source.
I'm not sure about their license, maybe try to contact them for more info.

Yeah. It would be excellent 👌.

I actually sent a message to them yesterday. They will reply, I hope.
