On one sunny day
She, who is endlessly wishing for
The fun beyond magic, is a problem

Suzumiya Haruhi no Yuutsu (涼宮ハルヒの憂鬱) or The Melancholy of Suzumiya Haruhi was one of the better anime of 2006. Not the best, mind you, but definitely one of my top 5. The ending theme Hare Hare Yukai (Sunny Sunny Fun) is generic J-pop fluff (i.e. not my idea of art or a good time), but the ending animation is strangely addictive, a guilty pleasure if you will.

Just found out recently that the voice actors each recorded a version of Hare Hare Yukai in character. Thanks to YouTube, I managed to listen to a few. Mostly rather mediocre (as I expected) but there is one gem, the Kyon version.

It has the bluesy, "unplugged" feel, and Kyon (Tomokazu Sugita) has a fine singing voice. Plus, the lyrics are hilarious for anybody who's seen the show, or read the manga or novels.
