"I'm A Barbie Girl" by Aqua.
For me, it really alternates between this and "Mambo Number 5" by Lou Bega. Something about his eloquence really speaks to a younger generation searching for themselves. More than Monica by his side, you're really hearing the paradoxical cry of silent injustices all around the world and a call to stand together. After all, whose personal narrative hasn't rang true within the lyrics of "I'm Blue" by Eiffel 65? Sing it, brother.
On a more serious note, http://www.youtube.com/watch?v=a_426RiwST8 The Black Keys- Lonely Boy has found me grooving to it quite often recently.
P.S. sorry for the terrible link-formatting. What am I doing wrong?
