Marié Digby singing "Rocketeer" (originally by Far East Movement)
Before Marié was a recording artist, she was actually a YouTube star. We love her acoustic rendition of this song by Far East Movement. She even raps a bit—which she loves doing, we found out when we met her a couple of years ago.
Sam Tsui singing "Hold It Against Me" (originally by Britney Spears)
Sam is another YouTube star we've been following. We love his mashups and this new video of him singing to Britney's latest single is awesome. We especially like the part when he samples "Gimme More." We hope it's true that Britney will perform at the Grammys!
