I am almost pretty sure this should be 87 BPM. While it doesn't change much, it's the true BPM of the song. Dubstep always has slow beats and high activity, so it doesn't change maps, but it does make the BPM correct (just don't forget to double all your SV values). :p
I am aware that many sites list it as 174 as well, but many also list it as 87, and pretty much all sites I found this track to purchase from labeled it as 87.
(No fear, just a number change, take a look at Kyoto for example)
Oh btw, I recommend offset +5, feels so much better.

Very fun, but some minor issues.
Take a look at this:

This slowdown is too sudden, making two notes completely overlap each other, as far as I know this is unrankable and should get fixed. Gradual slowdown recommended because the echo of the song stays for a bit longer at that part, so it would make sense.02:22:758 (1,2,3,4) - D kkd plays so much better (or d kkd) on many ways, just a suggestion.
Just don't think I am trying to undermine this, I just want it to be as best as possible.
