Most people didn’t become familiar with Luke James until he opened for Beyoncé on her latest world tour, but he’s been here for a while now.  An underground album as half a duo, then as an underground soloist, he is finally garnering some mainstream shine.  His new single (and first from his upcoming album) is about the turmoil of relationships and how it’s hard to decide when to leave and when to stay.  And Rick Ross (almost) manages to stay on subject with a pretty good guest verse.
