I think that One Piece has great music, especially for the intros. Sometimes the music can get quite stale at times. Purely because of the fact that it's been over 1000 episodes at this point and we're still using the exact same songs since the show's creation. Of course, there are some timeless classics in the One Piece Music Library. For example, Overtaken one of the main battle themes for the show will never get old to me. Because to me, this is a timeless classic, ever since Arlong Park back in 2005 I've found this song to be amazing. So overall I think that One Piece has an amazing soundtrack, although a little repetitive. And I hope that the anime team continues to make great tracks.
