Nightmare difficulty was recharted, altering its note count from 384 to 385.
Trivia
High was the only track from Week 4 that wasn't revealed ahead of time for its update.
A now-deleted Tweet made by Kawai Sprite shared a short snippet of what would eventually be this song.[1][2] This Tweet also seemed to show an early vocal test using two voices that do not sound like any of the characters in the game.
Originally, between 1:32 and 1:36 in the song, the notes were attributed to the incorrect characters. Boyfriend's notes lined up with Mommy Mearest's vocals and vice versa, making it appear as though they were singing each other's part instead of their own. This spanned all 3 difficulty levels. This oversight was fixed in the Week 7 update.
A similar situation also occurred during the next track, M.I.L.F, which was also fixed in the same update.
The word "high" is associated with both "uplifting" and euphoria resulting from drug usage.
ERECT High, Philly Nice and Thorns are tied as the only ERECT remixes that don't change the music tempo from their regular versions.
