Hmm, so I've been messing around with your new revision adding music in and out and I've noticed one thing: Saints Row 3 .wem music files are not being correctly read by the radioswapper while Saints Row 4 is being read perfectly. For example, I add in a song from Saints Row 3 and all I see once I've swapped it out is a 0 millisecond song. So I try making the milliseconds the amount that the song is and once I go in game there is absolutely no music, just silence. Now if I add in a Saints Row 4 song it works perfectly, I can see the milliseconds that the song is from the start and once I go in game it plays out the way it should. I'm not sure if there's a different method required for Saints Row 3 music as your tutorial focuses on Saints Row 4. I would think not but I just want to check!
