To people who don't realize, no close up during high notes because they're lip syncing, you can tell by the audio quality. It's too clean, it's impossible to be that clean while singing live.

@xxxyyy_ That is not an ad-lib, pal, an ad-lib has to be during a note. The mic can be on, doesn't mean that they're singing from the mic. Majority of lip syncing is the mic is on but nobody sings, and when they sing to pretend that it's not lip syncing then it's only a small line. That is the actual proof of lip syncing, one small line seemingly out of tune to the entire song. That part was live, but it was off tune, so pretty sure that they don't sing the entire song. You can tell by the audio quality that they're lip syncing, but this is even more solid. This is too clean to be live. Study.
