Sorry, I'm referring to...artists who aren't ashamed of (or too "sophisticated" for) their hits.
Oh please. We're post-Drowned World now. Re-Invention Tour was nothing but a greatest hits tour. Madonna has said, already like back in the 90s, that she just doesn't want to repeat what you hear on the record. And yes, like BBB said, you can refresh even your signature routines and songs. A better Madonna example: look what she's done with Vogue. It doesn't get any more "stylish video with a definitive theme" than that!
