Christina Grimmie is known as the YouTube sensation on The Voice.

Tuesday morning, she was a bit of an iTunes sensation as well.

Her rendition of "I Won't Give Up" was the best-performing song from Monday night's episode of The Voice on iTunes.

As of 10:30 a.m., the song had cracked the Top 50 on the iTunes overall chart and the Top 20 on the pop chart.

The next closest performer from The Voice on iTunes was Kat Perkins at number 135 with "Open Arms."

Two other singers managed to crack the Top 200 on iTunes overall chart. Those were Dani Moz with "Edge of Glory" and Tess Boyer with "Human."

When the playoffs opened last Tuesday, none of the Team Blake members cracked the Top 200.
