Its a mod, you have to download AC Content Manager first then be able to download the track.

Content Manager: https://acstuff.ru/app/
SRP Map: https://drive.google.com/file/d/10CBV8VRt9uBb1zKVMPZho8GCNbaaTeb1/view

If still not sure what to do, go youtube and search "Shutoko Revival Project Full Download"

how do you get that track??
