Re: SimMetal

 - I've not been able to find the actual audio files either. SimCity 2013 seems to be different from most of the other Sim franchises, there's no (easily apparent) way to change, add or listen to the audio files from the game. I did quite a few searches and was actually surprised to see the soundtrack for sale on a couple of well-known retailer websites. I don't know if you're enamored enough to pay for them, but try a Google search for "SimCity by EA Games Soundtrack" which may give a clue to the file names, at least. If I find anything in-game, I will definitely reply back to let you know
