The current options of event types in MusicBrainz does not adequately cover club nights or dance events where the primary performances are by DJs.

A concert typically involves one or more live acts performing on stage, with the audience facing the stage and attentively watching the performance. In contrast, a dance party or club night centers around DJ sets, where the focus is on dancing rather than watching a stage performance. Sometimes also referred to as a rave.

I was initially torn between naming the event type "Club night" or "Dance party", but I believe "Dance party" is the more suitable choice. While "Club night" is a common term, it strongly implies that the event takes place specifically in a club setting. However, DJ-led dance events are not limited to club environments.

The term "Dance party" is broader and more inclusive. Here is how Wikipedia defines the term.

A dance party (also referred to as a dance) is a social gathering where dancing is the primary activity. Some dance parties are held in a casual setting and open to the public, such as a rave, or those held in nightclubs.
