this time i know it’s for real - donna summer
never too much - luther vandross
oh no darling!/the king - sarah kinsley
run your mouth - the marías
and the ultimate romantic roadtrip song and probably the best song of all time: kiss me - sixpence none the richer
also not sure if this is of any help but when i’m on a roadtrip with someone and i’ve made a huge playlist, i like to shuffle and play a game where we rank every 5 songs from 1 to 5. it’s really fun and it makes time go by SO quickly
