One singer has one emotion, another singer has a wildly different emotion. They are probably apart and singing about their own situation.

Compare Lyrical Dissonance, in which the lyrics themselves contrast with other aspects of the song.

 * In the Central Park song Can We Do Today Again?, Owen sings about how he messed up being a father when he thought he would do a good job, while Paige sings about how she thought she earlier thought she doing a bad job being a mother and it turned out she was doing a good job. Owen wants this day to happen to start again so he would have a second chance and do it right that time; Paige wants the day to happen again so she can relive the joy of being so awesome.
 * This Bob’s Burgers song is technically a trio, but 2 of the characters are on the same page, so close enough.
 * In This Day Aria from My Little Pony: Friendship Is Magic Chrysalis sings about how her evil plan is going as planned while Princess Cadance, a victim of Chrysalis’s evil plan sings about how Chrysalis’s plan is proceeding well. Obviously they have different dispositions on if they want the plan to succeed.
 * Fun fact: Chrysalis and Cadence have the same voice actor.
