Outlaw Star is an older one, but still fun (I watched it again when I got the set a while back) and what I still contend is one of the most soothing ending songs of any anime.
It also has some lovely art during the end credits by a guy who also did classic Science Fiction covers for the Japanese (and some made it to the UK/US*), apparently the end art is meant to be from other stories by the writer behind the original Outlaw Star stories set in the same universe (of which the only other one to be made into an anime was Angel Links).
*I was surprised when I looked up his work to find several bits I recognised from books on my shelves (one of my favourite Isaac Asimov book covers included).
