St. Francis of Sales on psalms

I have a vague memory from years ago of reading a book written by St. Francis of Sales, which was a critique of protestantism (not one of his better known books of spiritual direction). In it, he criticized the protestant singing of the psalms (perhaps in their adaptation as popular hymns?), saying something like "A washerwoman or cobbler sits at their work singing sacred psalms, as if it's a ditty, with no respect for the holiness of Scripture and the reverence due the prayers."

Does anyone else have any recollection of this? Perhaps I've mixed up the author or the details. I'd love to re-find the reference.
