La vie en rose...life in rosy hues...
A song sung by many, but most popularly by Edith Piaf (in French) or Louis Armstrong (in English). I absolutely adore both versions of the song, but you can't beat the original in French. It inspires feelings wistful love, and a warm contentment and satisfaction with life. Here's one of my favorite covers of the song done by Pomplamoose on YouTube.
