Want to feel old? These 6 songs were released 10 years ago

OMG. Millennials can feel old now.

Six songs that were popular on the charts have now turned 10 years old. They include songs from Usher, Katy Perry and Eminem.

Here’s a look:

“O.M.G.” -- This was the third U.S. single from R&B singer-songwriter Usher and came from his sixth album, "Raymond Vs. Raymond.: The song features its composer and producer, Will.i.am, who was with Black Eyed Peas. The song hit No. 1 on Billboard’s Hot 100, making Usher the first artist to stand atop the Hot 100 in the 1990s, 2000s and 2010s, according to Songfacts.com. The only other pop stars to pull off the three-decade trick were Janet Jackson and Madonna, who did it during the 1980s, 1990s and 2000s.

“Love the Way You Lie” -- “Just gonna stand there and watch me burn,” Rihanna sings, accompanied by piano, in the opening of this song that paired her with rapper Eminem. The rapper told Skyrock Radio in Paris the collaboration was "one of those tracks that I felt like only (Rihanna) could pull it off, only she could do it.” The song was co-written by Skylar Grey, an American singer, songwriter, musician and record producer

“Firework” -- Katy Perry said the inspiration for this song came when, Russell Brand, her fiance at the time, showed her passages from Jack Kerouac’s “On the Road,” which spoke about liking people who are full of life and never say anything ordinary. The song spent four weeks at No. 1 on Billboard’s Hot 100 chart.

“Dynamite” -- This was the second single released by Taio Cruz, a British r&B singer. The bouncy lyrics and “aaayyy-oh” hook came from the international edition of Cruz’s second album, “Rokstarr.” The song was co-written by Cruz, who collaborated with Bonnie McKee and Max Martin. The “aaayyy-oh” in the chorus was originally a placeholder, according to Songfacts.com. Martin, while writing lyrics, would sing nonsense words while creating vocal harmonies. The songwriters decided to keep it in “Dynamite.” It worked.

“My First Kiss” -- This song was recorded by 3OH!3, an American electronic duo. It was written by Lukasz Gottwald, Sean Foreman, Nathaniel Motte and Benny Blanco. It was the lead single from the group’s album, “Streets of Gold,” and featured American singer/rapper Kesha.

“Like a G6” -- This catchy electro-pop song was performed by Far East Movement, a Los Angeles-based Korean-American foursome. The fast-paced song featuring The Cataracs, and Dev. Urban dictionaries define “Like a G6” as being awesome. Dev sings the breathy vocals during the song’s choruses.
