DJ Earworm
American DJ
Jordan Roseman, known professionally as DJ Earworm, is an American mashup artist from San Francisco, California, who has achieved recognition for his technically sophisticated, songwriting oriented music and video mashups. His annual “United State of Pop” mashup features the top 25 songs of the year, based in part on the Billboard's Year-End Hot 100 chart, in one mix.
Biography
Roseman was born into a big family of musicians and raised in eastern Iowa and Evanston, Illinois. At the University of Illinois, Roseman started as a physics major, before changing to music theory and computer science.
Roseman started creating mashups in 2003, which he said "was a relatively unexplored art form," with most people doing "A vs. B mashups [that featured] an a cappella of one song and an instrumental of another." He began by using ACID Pro, and after showing them to DJ Adrian at Club Bootie and receiving encouragement from him, Roseman created the moniker DJ Earworm ("earworm" referencing a song that repeats uncontrollably in one's mind) and began releasing his mashups online.
DJ Earworm's style involves gradually layering song samples over each other, which adds texture and builds momentum as a song progresses. In 2006, he published Audio Mashup Construction Kit, a how-to manual for creating mashups. Earworm uses Ableton Live and Adobe Audition to create his mashups and also DJs live with Ableton. For the videos that accompany his mashups, he uses Final Cut Pro X. In 2010, Earworm started VJing in his live sets.

Why this record matters
The phrase “american DJ” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 8, 2026. The linked authority identifier is Q1835994. VIAF identifies the subject as 58511726. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2003, 2006 and 2010.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
