"Say Something" explodes after Voice perf

"SAY SOMETHING" UPDATE: By the time it got dark last night, the AGBW-Xtina perf of "Say Something" had passed Marshall and RiRi to take the top spot on the iTunes Songs chart, and it's still there this morning—remarkable considering the prodigious appeal of Eminem at the moment (see next item). This is highly unusual, boys and girls, and a big moment for L.A. Reid's Epic as well as for these talented rookies. How long will David hold this lofty position over Goliath? Meanwhile, the online buzz continues; most recently, Perez Hilton has blogged enthusiastically about the song, the show and the band. Stay tuned...

We posted the preview below; here’s the performance itself. This instant phenomenon inspired OneRepublic’s Ryan Tedder to tweet, “Love it when a great song comes outta nowhere & explodes.” (11/6a)
