a style of electronic music that is not fast or lively, and is intended to make you relaxed and calm We are giving away a free copy of Pure Jazz Chillout! I love chillout music. It's a great way to lie back, relax and drift into another world. It's a loud club with space for dancing and a fully-equipped chillout room (= a quiet room where you can relax and listen to chillout music) at the rear.
