My son loves this song, so we buy every version that we come across. We actually heard it on Pandora, & it was quick & easy to purchase the track through Pandora. I think that's pretty cool. The Amazon mp3 player/widget works great from my phone (Samsung Galaxy S4).
I heard this on the movie "Juno" and loved it. I think there are many non-traditional, non-cliche pairings in this song that should make you think on a deeper level. Even the self parody at the end is thought provoking.
