Honestly, in my opinion, GTG is the only bad-sounding song live from FZ, where paradoxically it is my favorite song from the album. And this applies to the vocals in the chorus. The reception of music is a subjective issue, and many people don't like it, others love it. The problem is not that the singer can't do it, but that it's probably the most layered production song when it comes to vocals. Before they ever played this song I said on this forum that this song should not be played because of the vocal production (I believe that for a similar reason they never played Powerless) but evidently, they want to play everything in this era. I don't think the use of a substitute falsetto works here. But again, everyone has their own point of view, and others may like it. And here I admit that I said wrongly that they should abandon this song. Every artist is a decision-maker and will do whatever they want.
