For all those who saying that it not yg style or hybe style or anyone styles that an fanmade remember do not attempt anything perfect and for those who say yg use frist instrumental it not for Lovesick girl Solo Gone or Flower teaser it depends.
Jyp teaser will be hybe's teaser type becoz hybe hide their song and cheography...then hype's teaser is jyp entertainment's type becoz they spoil the main parts in mv's
the bighit one isnt accurate imo, usually bighit likes making the teaser sound completely different to the actual song, so most likely, they would use a bit of the instrumental from the bridge for the teasers audio
