This tag is for ambient or new age music.

Chill-out music (sometimes also chillout, chill out, or simply chill) is an umbrella term for several styles of electronic music characterized by their mellow style and mid-tempo beats — "chill" being derived from a slang injunction to "relax."

The genres associated with chill-out are mostly ambient, trip-hop, nu jazz, ambient house, New Age and other sub-genres of downtempo. Sometimes the easy listening sub-genre lounge is considered to belong to the chill-out collection as well. Chill out as a musical genre or description is synonymous with the more recently popularized terms "smooth electronica" and "soft techno" and is a loose genre of music blurring into several other very distinct styles of electronic and lo-fi music.
