“Comme d'habitude” (as usual) describes one day in a tired relationship. He wakes up, she's still asleep; he goes to work; he comes home late; she's already in bed; and they pretend, as usual, that everything is fine. Claude François co-wrote it in 1967 after his break-up with the singer France Gall.
Paul Anka heard it in France, wrote completely new English words, and gave it to Frank Sinatra as “My Way” — one of the most recorded songs ever. The French original is sadder and smaller.
It's wonderful for learners: the song walks through a day with reflexive verbs — se lever (to get up), s'habiller (to get dressed) — and the phrase you'll use forever: comme d'habitude.
