As for the distinction between Nightcore and Spe(e)d Up, I checked several ranked maps with these markers (both new and old ones) and apparently it's not true that only Nightcore Mixes have a higher pitch, most Speed Up Ver. songs do too.
Speeding up a song also increase the pitch (sound waves being compressed, higher frequency(?), sounds pitched up). Exemple with old cassettes, fowarding a cassette while having play button active sounds really high pitched. Most software nowdays offer to compensate when speeding up (often named as "tempo" instead of speed). So Speedup and nightcore do sounds the exact same, with exception nigthcore may add extra pitch if it's not pitched enough (song already fast)

I feel there needs to be a distinction between increased tempo and increased tempo+pitch. It does help when searching.
If we say that tempo+pitch is nigthcore and tempo is speed, at this point we'll get false nightcore for the above reason that speed = pitch
