Hey U

MAZO contributed "Hey U" as a new song in Pump It Up PRIME 2, part of the 1.07.0 update. Its problem was the timing: the same batch delivered higher-profile material such as Leather and BEDLAM, which drew most players' attention. As a result "Hey U" largely slipped under the radar, to the point that its wiki article was written surprisingly late despite the song having been in the game for some time. Running at 162 BPM, it keeps a low profile next to the era's bigger releases.

The song's main point of historical interest is its BGA, the last one produced under the Felnya name. After this work the artist continued contributing to the series under the alias MiLa through the early XX era, and is believed to have made a final BGA contribution with Can-can ~Orpheus in The Party Mix~ before stepping away from Pump It Up animation altogether. The animation's lead character is named Elena Kudrin, who had previously appeared in the BGA for Magical Vacation.

By PHOENIX data, the Single mode covers levels S5, S10 and S15, all charted by NIMGO, while Double mode offers D10 and D16, designed by DP4 KAHRUNYA. There is a small quirk in its difficulty history: the teaser video listed the top chart as a level 16, but it was lowered to S15 by the time the update shipped. Overall it is an approachable mid-level set with no pretensions of being a boss song.
