A disc jockey — known as a DJ — is someone who plays musical recordings at public events, nightclubs, radio shows, and anywhere else curated music is needed. A DJ is responsible for ensuring that both musical recordings and other programming like commercials and announcements play on time. They may also be responsible for interacting with listeners through social media. While the term DJ used to refer largely to someone working at a radio station, today, the term refers commonly to those producing their own dance music. DJs today may use vinyl records to perform, sampling parts of songs and switching between records using a mixer. A modern DJ may also use electronic music software like Ableton, Traktor, or FL Studio to mix and perform a party playlist. No matter what techniques and tools a DJ uses, the goal is the same: to provide an entertaining music experience for those in attendance.
