I'm not taking about being plastic for listening to them. I'm talking about their music.
Their production makes their sound sound like plastic. Waaay to much autotune, not a single real instrument, way to overproduced, and I bet someone else writes their lyrics since English isn't their first language.
Not to mention their songs are fairly simple. Very basic chord progressions and overused harmonies. I don't get the hype around them at all, unless you're a 14yo girl
