I'll come back and suggest
Space Battleship Yamato 2199 again. You liked Crest of the Stars, so I'm betting you'll like Yamato. Link has the trailer.
I'll also recommend
Maison Ikkoku again. It does start off a little slow, but it is one of the most satisfying romances I've watched. 96 episodes long and I've rewatched it four times. Still love to just sit and listen to the music.
Has a great soundtrack. Here are a few samples to whet your interest:
Bells Ring In The Dawn
Hello Sadness
Will There Be Sunshine Tomorrow
