Understanding the recorded work of most popular musicians — from rock to hip-hop, jazz to country — typically means perusing their albums and singles. There are exceptions, such as rappers' guest appearances: You don't really understand Busta Rhymes' importance if you don't take into account his verse on A Tribe Called Quest's "Scenario," for example. But even in an age of Web-bound one-offs, the primary discography and the classic album-tour template tend to guide pop's narrative.
Electronic dance musicians, on the other hand, keep their names afloat in a less linear manner: In dance culture, remixes and DJ sets — whether in clubs, at festivals, or on podcasts — are as important as albums and singles. A busy producer will scatter their work across multiple labels like crumbs. Limiting, say, Skrillex's work to his credited tracks leaves out his remix of Benny Benassi's "Cinema," one of his biggest tracks. When Storm Queen's "Look Right Through" reached number one on the U.K. chart in late 2013, it did so in the mix by house veteran MK.
