If you think performing in a giant bathtub is brave, how about telling Apple CEO Steve Jobs that his new service isn’t half as magical as he thinks? That’s the strong implication from the latest Bob Lefsetz newsletter, based on his meeting with Gaga’s manager Troy Carter. “I don’t want to tell tales out of school. But Jobs shows GaGa the latest Apple creation and GaGa says it sucks. Steve didn’t like this, he argued… So far, GaGa’s been right about that Apple product.” So what was the product? Ping is the obvious candidate, not least because Lady Gaga was one of the first artists to adopt it.
