I don't know how many people listen to so much of the discography as often as I do.
I do. I listen to music 90% of my waking hours, so although I'm not at all Homestuck-exclusive, I've probably listened to every song a dozen times or more.
And a thousand shames on the people in this thread who don't even listen to the music that's not in the comic.
Most of the best songs are not, or are cut down to small segments when used in the comic.
The real tragic thing about this piece is that it missed its only chance to get used. It was probably going to be used for the unfinished Rose/Vriska vs. Jack flash, but that never happened. Sad now.
Nah, it wasn't. There is an unfinished piece floating around one of the musicians' blogs that was supposed to be used. It would follow At The Price of Oblivion which would be used for Rose's part obviously.
But the biggest offender for a song that lacks a flash is obviously RDA. The good news is that the fans are making it!

Looks really promising if they can only get rid of some of the less talented contributors. Check out the google spreadsheet to see the finished bits.
