"Smile" by Nat King Cole
Just a little side note about this song (and really the reason I love it so much, besides the fact that it's just so good) is that Ren and I danced to this song on our first date. He was so charming, and I was gone in an instant. Like I said, it's a good song;)
I hope it can cheer you up too, if you're needing it!
What lifts you out of the blues? Any inspiring songs to share?
