DJ Earworm (aka Jordan Roseman) is a San Francisco-based mashup artist who has achieved recognition for his technically sophisticated, songwriting oriented mashups. His annual “United State of Pop” mashups, short mixes featuring the top 25 songs of the year according to Billboard magazine, have reached the Top 100 for national radio play and become internet sensations.

Roseman was born into a family of musicians and raised in eastern Iowa. In his early life, he played piano and produced original electronic music on a computer, later majoring in music theory and computer science at the University of Illinois. He began making mashups recreationally in 2003 using ACID. After encouragement from Dj Adrian at Club Bootie, Roseman created the moniker DJ Earworm ("earworm" referencing a song that repeats compulsively within one's mind) and began releasing mashups via a website.
DJ Earworm has a unique mashup style that consists of a compositional, songwriting approach. He gradually layers samples on top of one another, matching keys and subtly altering melodies. His mashups often convey an entirely new meaning than the original material, such as a political message in “No More Gas”. He has been contrasted with mashup artist Girl Talk, who has a more DJ-oriented style.
He is the author of Audio Mashup Construction Kit (Wiley, 2006), a how-to manual for creating mashups.
At the 2008 IDEA conference, he revealed that he has made mashups using Ableton Live, and now DJs live with the same software.
