What's favorite Anime?

Just as something different and hopefully fun, I was wondering if anyone had a favorite ( or several favorites ) Anime? Any songs you love from one?

Just a few for me are :

Clannad and Clannad After Story

K-On ( just all over cute and fun )

Fairy Tail ( LOVE the music )

Ran ma 1/2 ( Never go wrong with the classics )

That's only a few I have seen and enjoyed but I am allways lookign for more!
