Wasn't 100% sure about this at first, but after repeated listening I think you're right. That's the last one, cheers to ya for completing the list! Speaking of which, here's the completed list of "Uuh" samples:
ORCH2.wav (Fairlight CMI IIx orchestra hit)
"THIS! IS! SPARTA!" (from the movie "300")
Theme music from Bod
Night Fever by The Bee Gees
Gangnam Style by PSY
Relax by Frankie Goes To Hollywood
Amen, Brother by The Winstons (the famous Amen Break)
Wilhelm Scream (another famous stock sound)
"You're gonna be a bad motherfucker" (from the movie "Robocop")
Boogie Wonderland by Earth, Wind, and Fire
Believe by Cher
Take On Me by a-ha
Beat It by Michael Jackson
Blue (Da Ba Dee) by Eiffel 65
"Half-witted, scruffy-looking nerf herder!" (from the movie "Star Wars - The Empire Strikes Back")
"See ya at the party, Richter!" (from the movie "Total Recall")
20th Century Fox logo music
the intro bit from Red Moss
The main surprises in here are obviously 300 and Gangnam Style, the rest of these seem pretty in-character for a Hell Interface type project. I wonder if they've secretly done some other project which heavily draws upon "the classics" that they can't say they were behind because it's full of samples that would cost a fortune to clear like these ones? Probably just wishful thinking on my part
In any case, now that we've tracked down all the samples this may as well just become the dedicated "Uuh" discussion thread since anything in the General Speculation one will inevitably get lost in the shuffle after a couple weeks. Would rename it myself but I can't lmao, if one of the mods could change it to "'Uuh' sample hunting/discussion thread" that would be swell. Also anyone here is free to use that list for whatever they'd like, including maybe putting it on bocpages if they're so inclined. Maybe a general article about Sheol Boundary and why it's generally accepted as legit would be a good place to talk about it?
