Last year I listened to shadows and trickery from Payday 2, but seeing how the event has seemingly unchanged since last year this might be more suitable.

^ Reminds me of this video I found a while ago. DISCLAIMER: Not meant to put down your interests.

Can't go wrong with some Mystery Skulls or Justice. The beat helps with speedruns imo, keeps me going at a nice pace.

I personally love a lot of the Payday 2 soundtrack, shadows and trickery being a favorite with both Hot Pursuit and Evil Eye. Breach 2015 may also be a good soundtrack to listen to as well.

After a little while I may go back to listening to these soundtracks on loop. For now, I'm just liking the music of Candlestick Keep. I'm sure it'll get bland at some point, and that's likely when I'll start listening to these soundtracks.

Ask this guy

While you run through alone in the dark alone so that you can cheese the event as hard as possible and make it just barely unbearable-

And then towards the end of the event when you haven't found anything you can shift over to some nice-

When I read "Hot Pursuit", this is what came to mind at first. It actually does make the hunt more exciting to listen to.

Then, naturally enough, the train of thought brought up this track to mind when I got to thinking of spotting a Black Kat.

Two Steps From Hell + Touhou =Tutti Sound
:D

This event I just sort of stumbled across a few 10-hour loops so I can sort of track my time while playing. Here are some of the tracks I've been listening to, whether or not they actually are something suitable for farming black kats to.

Feel the Melody by S3RL. (Hit the 3 hour mark)
Pika Girl by S3RL. (Hit the 5 hour mark)
Nya Nya Pikachu by vampiress892. (Haven't listened to this one too long, was in suggested search from Pika Girl and I'll likely be listening to it sometime in the future)

And a non-10 hour mix list:
Never gonna wake you up by NilsOfficial.
I Can't Decide by Scissor Sister. (1 hour loop on this one)
Walk The Dinosaur (Sim Gretina remix) by, take a guess, Sim Gretina.

Those are all that I think I've been listening too. Other than that, the default candlestick keep soundtrack, talking to friends on skype, or watching the Game Grumps hate each other in Super Mario 3D World is my grinding life's background noise.

Like do you want a gmaing dubstep playlist or a heavy metal playlist or an orchestral playlist?

I love your style, Oroseira. Tohou is the bomb digity, as are Tohou remixes. With the amount of time I've dedicated to grinding, I've pretty much made it through my entire library of music by now.
