A whole new set of Sound Room tracc's. The fake ASMR track & the "Lo-Fi Wario Guy" tracks I shared some time back are a couple that I made specially (planned to replace Avocado Song and The Short Futon, respectively) but beyond that we also have a MIDI recreation that I did (and stupidface did QA on) of Colonel Carloft's "Even More WL4 Stuff" for Crescent Moon Village/Yesterday's Words, a Waarangement of Eminem's Cleanin' Out My Closet for Mystic Lake/Tomorrow's Blood Pressure (because the main EP riff used sounds a lot like the end section of ML's outdoor theme). I've got a few more ideas beyond that, though, like
"And I Love Her" by the Beatles for Wildflower Fields/Things That Never Change;
"Star Maze" from Mario Land 2 for 40 Below Fridge/The Moon's Lamppost (because kek);
Driftwood & the Island Dog I'm thinking about making into the Wind Waker opening theme, and have it be like a bait and switch (if I can get it to work the way I plan-- otherwise it'll be a trimmed down version of my Voya Nui Bay waarangement from BIONICLE Heroes DS;
"New Junk City" from Earthworm Jim for Toxic Landfill/Soft Shell ("but wait!" I hear you say. "Soft Shell is the Pinball Zone CD!" To which I say "yes, but
The Judge's Feet I'm wanting to turn into that Royksopp song from the Geico Caveman commercial, and also since when do WL4's CD's match the level they come from");
I plan to make Beyond the Headrush into one of Ocarina's temple themes, possibly the Shadow or Water Temple, maybe Fire (feel free to weigh in);
Mr. Ether & Planaria I'm working on making into the Wally battle theme from MOTHER/EarthBound Beginnings ((God I hate the English name));
uhhhh and that's all I've thought of at the moment. Oh yeah, and Forest Whitaker by Brother Ali for Palm Tree Paradise/About that Shepherd, although it's intended more as a spiritual Hall of Hieroglyphs CD, for reasons that will become apparent once heard. This was sent to me by an acquaintance of mine after we found out the other liked Em's music, and as I listened to it, I realized that this is literally the exact kind of song you'd find on one of those Spotify mix tapes 20-something girls make for specific characters, fucking number one, only the character in question is Wario. So, not only does it sound like pretty Hall of Hieroglyphs, but the words also work as if Wario wrote them.
Edit: I just got an idea-- it may be possible to replace the Medamayaki karaoke track without also replacing Palm Tree Paradise, as I think there is a 2nd MIDI in the game's files for it. If that's the case, I'm going to make that the Brother Ali song instead.
