Wim van Beek at the Schnitger organ of the Martinikerk in Groningen playing Georg Böhm's "Freu dich sehr, O meine Seele" - "Rejoice, O My Soul", one of my absolute favorite pieces of Baroque keyboard music. My ex played the hell out of this on the Flentrop in Duke Chapel, especially the penultimate variation which has the cantus in the pedal which begins at about 7:40. Thrillingly hair-raising. This is the closest version to his that I've been able to find on the web. 

The Magnetic Fields' collection of 69 Love Songs is just brilliant. Little delights, each one. 

And if THIS doesn't lift your spirits, nothing will!  I can only guess how much rehearsing this took. Hilarious. I smile every time :-)
