I Just Don't Know What to Do With Myself. The songwriting on this one does a create job of shifting from frustration to anger. The verse having that waltz-like bounce that alludes to a romantic dance (in my head) is super cool.
For me its songs like I wanna be the boy to warm your mother heart and got her in your pocket that really show a underlying insecurity but this album and Jack's writing in general tends to have this passive aggressive self depreciation, sarcasm that tend to mix with tender moments of insecurity and child like love and affection
