Sorry for double posting.
The purple-black checkerboard on the ramps are suppose to be there. I wrote "LOL, missing texture" on it so...yeah...
The bsp file size is so big because of the mp3s packed in the bsp. It's annoying but I tried to make the songs short and have moderately-good quality bit rates. I might make a version of the map without the music files for those who don't want to mess around with the music player.
Music is played via the brushes on the giant weighted companion cub in the middle of the map. The list of music/sounds includes:
"I believe you have my Staper"
"You're the man now, dog!"
Punchout (Spy Sappin' my Sentry Remix)
Max Coveri - Runnin' in the '90s (LOL, internet)
Danny Elfman - Breakfast Machine (from Pee Wee's Big Adventure) (with TF2 voice overs added to it)
El Chombo - Macarron Chacarron (Batman Ualuealuealeuale song)
DarkMateria - The Picard Song
Coburn - We Interrupt This Programme (Jean Claude Ades remix) (NEDM)
