fmodel, can't remember which .pak file it was in but the filename is 45357622.wem This was actually in the game's files before the shop was available to everyone, not sure if it was in the files right from launch though, could have been in a small update patch before the shop was available.

Wow, that's a great music coming from this massive disappointing shop feature Tekken 8 had to offer. It would be amazing to replace the customization music with this one.
