When was the last time...

...a TV show theme song had an appealing bluesy tint and was allowed to breathe?  This came to mind while watching a first season episode of NBC's "A Different World."  Phoebe Snow's vocals lay out the show's high school to college transition premise in no great hurry and allow for an instrumental interlude.  Today, a viewer is lucky to be given even a few notes to set the scene of any program.
