Naruto has been praised for its music by many, so I'm just curious what everyone's favorite Opening or Ending themes are. Many of them have been pretty damn good, and stand as great songs all by themselves. I'm not suprised if most people's favorites are earlier ones, though. Some of the more recent ones have sucked...kinda badly.
Since I know everyone else is gonna say "Haruka Kanata" was the best OP, I'll list "Seishun Kyosokyoku" as my favorite. It's really upbeat, and I like the kind of 70's funk the guitar parts have. I also really like Sambomaster (the band). The lead singer is pretty good and has a distinctive sound. The animation that went along with it was also really dynamic, showing all the characters running/jumping/fighting. Watching it always got me pumped and ready to watch the episode.
My favorite ending theme, by far, is "Ima Made Nando Mo". For some reason I really love the full version of that song. The lead singer is so awesome, and the piano and organ parts they integrate into it are great - especially at the very beginning and very end. I think they fit so well. It's also got this "epic" feel to it (at least, morso than the other EDs), so it's a really memorable song for me.
Let the wave of "Haruka Kanata" responses roll in!
Edit: Also, feel free to list what you thought the worst themes were too.
