On the Deltarune Wiki it's "Hidden", but on the Undertale one it's "Unlisted". Is there a reason for them differing?
It's harmless enough but it's just a bit weird since it's the only pagename I can think of to differ quite like this.
Personally, I feel like "unlisted" is the better name. They're not really hidden if Toby has put them in livestreams, game files, ETC. It's still not an ideal name, just the better one.
They are stillhidden in the game though. For instance, man.ogg is in the game but not in the soundtrack, and you only hear it in-game of you can find the man's room.
From what I recall, we haven't gotten around to moving it yet. Photon had suggested "Unlisted" as an alternative to "Hidden" a while back. At the time, I once had some concerns about it probably getting mixed up with "Unused"... not so much anymore. Wabo Webi was the one to make the "Unlisted music tracks" article for Undertale Wiki sometime after.
It might be fine if we move it and leave Hidden music tracks as a redirect, also so both are consistent with each other. We'd have to double-check on redirects too, of course!
I think unlisted would probably be the right way to go about it...
I think we should go with unlisted here. We just haven't gotten to renaming the page on DRW.
