DJ Room

 is one of the Locations in the game The Metronomicon.

Summary
The DJ Room is where the player can spend their elemental crystals to buy songs for further listening. Don't worry, whatever elemental power stored in the crystals has already been used to level up characters' abilities, so they are free to be spent rather frivolously.

The room must first be unlocked in the Workshop.

After a song is bought, you can play it back and listen to it. Note that some of the songs have been edited so that the in-game track flows better - and the DJ room plays these edited versions. Note also that the program mutes the audio if it loses focus, so it's not possible to do other things while listening to the songs.

Besides songs, cutscenes can also be bought should the player wish to rewatch them again. (They're quite funny.)
