OMG (feat. will.i.am)

Thanks to the rise in social media and the ubiquity of texting, the shorthand OMG ("Oh My God") was everywhere in 2010, including in this pumping anthem to hot-looking ladies. It features Will.i.am from the Black Eyed Peas, who wrote and produced the song. Usher probably wouldn't write a lyrics like this, but the man who gave us "My Humps" sure would: Honey got a booty like pow, pow, pow Honey got some boobies like wow, oh wow

"OMG" was the big hit from Usher's sixth album, Raymond Vs Raymond. It was his fourth #1 hit in the UK (his first since "Burn" in 2004) and his ninth #1 in America. Usher's run of US chart-toppers started on Valentine's Day 1998 with "Nice & Slow" and continued until March 2010 with "OMG." No one else had more #1 hits in this span - Mariah Carey and Rihanna had the second-most with six each.

When "OMG" hit #1 in America, it made Usher the first artist with #1 hits in the 1990s, 2000s, and 2010s. The only other artist to do it was Britney Spears. In the 1980s, 1990s and 2000s, only Madonna and Janet Jackson accomplished the feat.
