iTunes shuffle mode was in strong form for me today. I was pleased to hear "Good Things" by BoDeans flow into Tom Petty's "A Higher Place." The lyrical honesty and optimism of both tunes makes them compatible; in both cases, the singer is essentially saying, "This relationship might not be perfect, but there's a solid enough foundation here on which to build."
As a bonus, "A Higher Place" segued randomly with "River Rise" by David Crosby featuring Michael McDonald. Musically, Petty's tune flows smoothly into Crosby and McDonald's track, so I'm surprised that I've never heard that segue on any radio station or stream.
