The potential upside to PANDORA's $450 million purchase of TICKETFLY is obvious and huge: Make it easier for touring artists to connect with fans around the world, and for fans to find out about and get into shows, and that's a big win for everybody. But there's a potential downside too, should PANDORA decide to leverage its new asset in another way: Imagine a future where you have to be an active PANDORA user to get good seats for the BLACK KEYS. And maybe you have to be an APPLE MUSIC subscriber if you want to get the best seats for DRAKE, and a YOUTUBE subscriber if you want to have any hope of getting into that KANYE WEST show. That's a scary, but plausible, future. So my plea to PANDORA: Build bridges, please. Do not build walls... One of the best NICKI MINAJ interviews you will ever read ends with MINAJ cutting the interview short, kicking the interviewer out of her hotel suite, and the interviewer understanding -- and accepting -- exactly why... Speaking of which: STEPHEN TOBOLOWSKY on "ANACONDA."
