Take Lee Hi's last comeback for example:
The pre release track Only peaked at #93 on Gaon while the title track Red Lipstick peaked at #30. Red Lipstick also made it to #22 on Billboard's World digital chart.
Now about six months later Only has 44M YouTube views while Red Lipstick has 9M views. Only has over 100M Spotify streams while Red Lipstick has over 8M.
Obviously Only is the more successful song but it has the lower Gaon peak and never made it on Billboard's World digtal chart.
