Today, a secret camera embedded in a video screen on a kiosk at a TAYLOR SWIFT concert can use facial recognition technology to identify potential criminals—specifically, people believed to be stalking Taylor Swift. Tomorrow, presumably, that same camera will be able to tell marketers, advertisers and political campaigns where everybody is all the time, where they're coming from and where they're going, and the information will be used to sell you stuff and try to influence your behavior, and you won't necessarily be aware it's happening. The camera, that is, will be stalking you. This is as inevitable as the fact that the sun will come up and come down at some point tomorrow. Look what we made that camera do, we will say. Stalkers should be chased down and rooted out, no argument there. Both kinds, though... The ROCK AND ROLL HALL OF FAME class of 2019 will be announced today and, as has been the case for the past few years, there are no automatic, can't-miss candidates on the ballot. No NIRVANAs, no ALLEN IVERSONs. We've run out of those, at least for a while. I had thought RADIOHEAD, who hit the ballot for the first time a year ago, was a given, but I was proved wrong. The voters' distaste for British people under the age of roughly PETER GABRIEL remains strong. The hall's nominating committee doesn't put up bad candidates: All 15 acts on this year's ballot belong in someone's hall of fame, but none belongs in everybody's. My ballot: KRAFTWERK, JANET JACKSON, ROXY MUSIC, the CURE, RUFUS & CHAKA KHAN. Makers of classic, enduring, influential pop music, all of them, and ready and able to fill in glaring blind spots and long-neglected holes on those walls in Cleveland... TENCENT MUSIC IPO'd Wednesday with a modest $13-per-share price and closed the day with a modest gain, at $14.10. Some analysts noted that leaves the company valued at significantly less than it was a few months ago, while others said it was a relatively successful public launch after a rocky lead-up. "Disaster averted," said CNBC... I feel the pain of anyone trying to make a living writing about music—or in any kind of journalism—in this age of disruption, distrust and dispiriting paychecks. I'm not sure, though, I'd blame "a machine-driven world that rewards artists not for their originality, creativity, or emotional authenticity, but for their ability to replicate proven, predetermined formulas." If that was the culprit, music journalism would have stopped mattering decades ago. But CHERIE HU's examination of the various other ways an "algorithmic culture" is disrupting the music critic trade is worth the read if you can tear yourself away for a few minutes from that algorithm-based playlist you're half-listening to... WFMU's FREE MUSIC ARCHIVE has found a new home... ATLANTIC RECORDS has "parted ways" with rap podcaster-influencer ADAM "ADAM22" GRANDMAISON and his NO JUMPER label amid accusations of sexual assault, which he has denied... Sync of the week: DEATH GRIPS soundtracked the destruction of PRESIDENT TRUMP's HOLLYWOOD STAR... Bands we lost in 2018... RIP J. LYMAN POTTS.
