Quoted from PoMC:
That's something so cool about Mustang. Add the driving/pinball tunes that YOU want to hear.
For sure. It's cool that of all the Mustang pinballs in the world, mine is the only one that sounds like this.
Little tip for people customizing music: Not all songs work for pinball. I actually tried a lot of different ones. A lot felt flat and didn't have pinball energy. Pinball also doesn't give songs a lot of time to build. I'd suggest editing songs to start with their chorus, giving them time to build doesn't really work, depending on the song.
And for Mustang in particular, a few of the samples are not long. Police Pursuit in particular, I think for the first part of the mode, is about a 1 minute sample. So you want to find something that can loop well, then you have the 2nd half of police pursuit.
But the music customization of Mustang is so unique because it isn't tied to the theme at all. It's your personal radio.
