200% volume. me atm.
If your ears listen to that at roughly 130 db or worse for even one split second, it would likely be painful and very angry neighbors of course.
Being a champion of all four in FH4 just never been that stressful, but despite the mood the song supposedly depicts, it actually make me want to chime in. Of course, no matter what song I want to listen to with so many restarts, the A.I. does not care.
I even had a humorous reference encounter to the trend of "tryhard players" by facing up against an AI racer named "Try Water" for nearly the entire race in the longest 1v1 way out in front, his Ferrari vs. my Nismo '95 whilst listening to this. The game does allow any song to loop only the action part, not the full length for a few times to keep you in the racing mood, but after that it will advance to the next track eventually on very long races.
Skip the first minute for the action sequence for best results.
