I listen to a lot of French popular music, but doubt that most non-french would care for the music and/or the recording quality.
Much of his stuff is corny, but my most recent purchase was a 13 cd box set of Jean Ferrat covering "most" of his work from 1961-1972.
These were remastered and recording wise sound good.
I also have this work in an LP box set which contains material not released with the CD set.
Listen to The Umbrellas of Cherbourg @ least once a month.
You might also look up Francoise Hardy (I only have one album that my wife purchased).
If I'm in the mood for something that resembles English my go-to is Joe Cocker.
