I love Sam Tsui. I’m weirded out that he looks like one of my ex-boyfriends, but I love him. I love his cover of Jay Sean‘s Down. I love his If I Die Young by The Band Perry. I love his Need You Now by Lady Antebellum. And now — like more than two million other YouTubers — I love love love his cover of Britney‘s Hold It Against Me. Like, I love it waaaaaaaaaay more than the original.
