There are so many contributing factors as to what makes a good anime great, and the music has a lot to do with that. Which ones do you think have the best music?
The top of the list for me is the soundtrack for Gravitation. It's extremely upbeat, very catchy, and does a good job enhancing the story.
2nd is Inuyasha and Hunter x Hunter. They have great intros and endings, and the background music fades in well and doesn't get repetitive.
3rd up is Kenshin, which has good music all around.
