"Last time the miscarriage was so tragic/We was afraid you'd disappear/But nah baby you magic."

When YouTube unveiled its slate of new channels to advertisers in New York City on Tuesday night, the Google-owned company enlisted none other than Jay-Z to close the event with a song we've all heard before but was oh-so-appropriate: that's right, "Empire State of Mind."

The buzzy hot ticket, held at the Beacon Theater on the Upper West Side, also had performances by Flo Rida, Pharrell Williams and the Neon Trees. Over the course of two weeks, at the "digital upfronts," YouTube and other online giants are pitching original programs to the ad industry, TV-style. For its part, YouTube --- dubbing its presentation "Brandcast" -- announced it would pour $200 million into promoting the launch of such channels as "WIGS," which is geared toward women and will feature series starring Julia Stiles and Jennifer Garner, among other big names.

What, no Jay-Z?
