The idea is for a club to hold parties with the music adapted very specifically to the taste of the visitors. This would be achieved by analyzing the selection of people's favorite music on online streaming platforms (with their consent), grouping people into different categories accordingly, and inviting each group to a different party specifically designed to match the taste of its guests.
Just to make it clear, I'm not trying to say that people who like pop and house more will be invited to a pop-house party and people who like drum & bass and dubstep will be invited to the party playing those genres. Different clubs/events exist for this purpose. The idea is to make it way more specific.
If you like techno and go to the club that plays predominantly that genre, you can still either enjoy the music at a certain party or not really, this depends on the playing Djs and the specific sets they chose for that evening. The way to make the set more personalized is by adapting it to the defining parameters of your favorite music.
How would it work: The club advertises that they will be holding personalized parties and invites people to participate. For this, you'd have to register on the club's website and link your profile(s) of an online music streaming platform(s). You could then indicate your favorite dance music by linking specific playlists, artists, albums, and solitary songs. The more favorite music you'd provide for the algorithm to analyze, the better understanding of your general taste the organizers will be able to get.
Software similar to this could be used for music analysis. It would analyze all the music indicated by the user as their favorite and then dredge out the defining parameters, such as BPM range, dominating keys, dominating mood of the songs, etc. All the registered participants would then be grouped into categories according to the best matching/approximation of those parameters.
The Dj(s) would see the defining parameters of a certain group and would adapt the evening's set accordingly. Also, different Djs could be assigned to certain groups by the organizers according to the parameters of the sets that they usually play.
Different groups of people could either be invited to the same club on different dates or, if the club had a few venues, they could be invited on the same day to different venues.
An opportunity for a novel club business.
Attract more people to the venue(s) by increasing the chances that they will enjoy the played music.
Visitors can be more certain that they will like the sets played at the party, therefore less frustration trying to decide if you want to go there or not.
At the party, you are more likely to connect with people whose taste in music is similar to yours in a specific sense.
The anticipation of being assigned to a specific (initially unknown) group ads a gamification element and is an attractive concept marketing-wise.
