I wanted to like the track "rainbow" but Liam's voice sounds weirdly out of time yet in time. I think it's the way it's been produced in the daw. computer.
Each line sung and composited together. It kind of sounds too quantized. Just like when drums have no humanisation or swing to them
I know his isn't a recent trick to use but when it's not done correctly it sounds obvious.
I'd also go so far as to say with his recent stuff it sounds like he has sang a bank of words and phrases then pieces then together when needed, again probably a common studio trick . Just like double tracking et all
