Try this: See how many music files there are in the two Radio folders (about 35 in total), choose the same number of your favourite mp3s, copy them to the Radio folders, remane your mp3s according to the existing music files, delete the old music files. When you start up the game, your music will be playing ingame!!! Amazing stuff!! Probably won't make the game load faster, nice if you want to listen to your own music, but saves RAM not having a music player open whilst loading the game.. I guess...
