How can I listen to Independence FM outside GTA IV?

Question

I really enjoy listening to Independence FM in GTA IV. In the game, it's a radio station with custom music that is picked from a folder. I would love to be able to listen to it on my phone whenever I'd like to. I have tons of music on my phone as well as all the folders with intros and outros to songs, commercial breaks, and commercials themselves, same for the news, id jingles, and comments by DJ.

After driving around and plainly sitting in the car in the game, I came up with a note about in what order different audios are played. Here I tried to visualize that: With all of that done, I encountered one big issue: I have no idea how to code this. This requires skills far beyond my tiny knowledge of Python and C++. Not only this has to be able to play audios from multiple folders, but it also is probably going to end up being a mobile app. This idea is to grand for me to do. At least with my current programming skills
