It's really hard, I don't know. There are songs we like for the lyrics, other for the music or both. I would probably choose some very old song in French for their lyrics. Some song nobody heard of, and doesn't care about, Like "Élégie" from Plume or some more popular like "Il n'y a pas d'amour heureux" "Ne me quitte pas" or "Mistral gagnant" although the lyrics are a bit funny. For the music, Clair de Lune is certainly really pretty, younger I was often listening to Eric Satie, especially "Gnossienne No.1". Then I think to some English oldies like "Smile" or "Lilac Wine", and more contemporain songs like Patrick Watson's "Great Escape", "Lighthouse" or ...there are just so many, how can I choose?
