I Just walked past a white convertable full of ladies blaring J-Lo’s “Love Don’t Cost A Thing.”I’m a big fan. No shame. But, like most of summer’s greatest hits, it can only be played between Memorial Day and Labor Day, only from your car, and only on sunny days. I think Aja found a new single for this summer. Other top performances on my summer roster: Beach Boys, “I Get Around”Jim Noir, “My Patch” Who am I missing any?
