one song, every phone

Turn the phones in the room into one speaker. Same song, same instant, no lag between them.

Everyone needs to be on the same wifi or the same link. Whoever starts the party runs the music; everyone else can play and pause, and can be given the rest at any time. Every phone downloads a track before it starts, so nothing is ever streamed late.

If this phone sounds slightly behind the others, drag right until the clicks land together. Every phone takes a different amount of time to push sound out of its speaker, and a bluetooth speaker adds a lot more. The clock cannot see that, so this is the fix for now.
