ya but it is possible to tell the difference between a composition you don't like and a composition that is not well written. regardless of your personal tastes.
i work in audio and get this issue a lot, music composition always trumps the sounds quality and mix, so if the band im working with wrote a bad song it doesn't matter how much work i put into it, and it doesn't matter if i give them the best instruments and mics to use, it will still be a bad song just a polished bad…
