Junk
Veteran producer Junk has been making music for almost as long as osu! has been a thing. Since 2009, Junk's repertoire of trance, house, and EDM tunes has been on the rise, especially among rhythm game communities. Fans of SOUND VOLTEX, O.N.G.E.K.I., and CHUNITHM have heard Junk's sound before, and circle clickers are here to officially bring Junk in osu! too.
Given Junk has been producing music for a decade and a half, it's no surprise that they've already made a name for themselves in the osu! community. Qualia was first mapped in 2014 by some osu!mania creators, launching a trend of Junk that still hasn't stopped. Junk conveys a classic-feeling rhythm game style, so if that's what you're looking for, open the editor already.
