Never watched Naruto, or Fairy Tale or Bleach or any other 100+ episode anime series. Don't really have the time or the interest.I just recently got into anime and FMA is on my to watch list.
But some beautiful music from Naruto may perhaps also satisfy you a bit
But FMA:B is the best shounen Anime I've ever seen and perhaps my favorite anime series to date. And I put emphasis on favorite. Cowboy Bebop is still hands down the best series I've ever seen. The soundtrack is also so much better. I only like the FMA:B soundtrack in the context of the awesomeness of the series. But Bebop's soundtrack is fantastic on its own.
If that makes any sense..
