For a modern setting, try
Nodame Cantabile. If you're open to a fantasy set in more ancient times,
Tale of Saiunkoku is a good choice.
Cross Game is a romantic comedy about teenagers who love baseball. Many people here think it was one of the best, if not the best, series to air over the past year or so. VIZ has begun streaming the episodes
here, though they have only released twelve of the fifty so far.
