curious how you keep the lyric highlight in sync across players given this is browser audio, not a native client. each phone's audio pipeline has different buffering (bluetooth headphones alone can add 100-200ms of latency depending on the device), so if the highlighted line advances off local playback position rather than a shared server clock, two players on the same "beat" can end up seeing different words highlighted, which matters a lot for a game about lyrical timing. also on iOS safari specifically, an audio element started from one gesture and then paused/resumed later (someone switching tabs to grab a drink) can get stuck needing another user tap to resume playback, which for a fast round based party game would just look like the game silently broke for that person mid round.
