My friend Tom pointed me at this video for the song "Lollipop" by Mika, whom I hadn't heard of before. I can take or leave the music by itself, but mixed with this Peter Max-meets-Tex Avery animation from the French studio Bonzom, the result is three minutes of overwhelmingly positive energy (and just a little bit of naughtiness).
If you're like me, you'll watch it through, and then watch it through again, and the whole time feel a desperate need to see it through some channel other than YouTube's teeny tiny blur-o-vision. Here's one link to a less cruddy version. I ended up buying the video from iTunes for $1.50. I've vaguely wondered for a long time what would move me to spend ten bits on a music video, and now I know.
(Postscript: Have also taken to dropping two-dollah bills on Cartoon Brew Films' offerings, lately.)
