I think it would be easy to a “now playing” sign much like the theater has to the Nightclub, additionally you might show the number of patrons inside; Either of these changes would help players to know when the nightclub is active and encourage them to come inside (more often than not it’s totally empty.)
Also please fix the VFX, I miss the waveforms allot 
(I’m aware this is probably because Soundcloud altered their API but still.)
