I havent had TWC since March 23 but have been keeping tabs on here... seems like there are quite a few vocal tracks on this playlist... or at least a lot of vocal CD's listed. I suspect NBC is just trying to appeal to a certain demographic (young women and/or the female audience at large), which most U.S. corporations do, and switch the TWC LF genre from Jazz to Primarily Rock or Techno might just be one of those moves in that "marketing" ploy. It doesnt make sense (at least at first glance) b/c it is weather related, but then again, I could be wrong
