Everywhere you look, singers vocals, instruments, beats, everything is made to be perfect. Everything is overproduced and fixed to sound perfect. Sometimes things sound good the way they are. Here is a great example. Living On A Prayer with lead and back vocals, no music.

This is what you would hear if you were in the vocal booth with the band. If you listen close you can hear each member have a specific part. They could still re do things to make them right, but this was before you could cut and paste and fix vocals.
