10 Most Downloaded iTunes Songs of All Time
In celebration of iTunes' 10 Billion download marker (which was met on Feb. 24, 2010 at 9:43PM GMT), Apple has revealed the Most Downloaded iTunes Songs of All Time. Covering singles from Kesha, GaGa and the Black Eyed Peas, among others, these iTunes singles prove that when it comes to downloading music by the masses, we chose to fill our iPods and nanos mostly with retro club beats and dance-floor jams -- but also muse over romantic ballads by Jason Mraz and Taylor Swift, even the string-driven melody in Coldplay's 'Viva La Vida.' Check out the entire list of songs (all released within the last few years) after the jump!

Kesha: 'TiK ToK' (2009)
Featured off her debut album '
Animal,' this iTunes single -- with auto-synth back beats -- muses about the singer's crazy night out partying. The chorus is a definite party rocker: "Don't stop, make it pop / DJ, blow my speakers up / Tonight, I'mma fight / 'Til we see the sunlight..."
The 2006 'X-Factor' winner released this R&B/pop track as her lead single off her debut 'Spirit.' Although it is considered a love song, the song's structure is more R&B danced-based (with wood block percussion and synthesized strings) than a slow-tempo ballad. This song not only made iTunes top 10 most downloaded list, but was the best-selling single in the U.K., as well as the top selling track of 2008, according to Nielsen SoundScan.
She may not have perfect pitch, but she sure can write, sharing the perfect love story that every girl would want, lyrically tying in the story between Romeo & Juliet (sans the tragic ending, obviously): "Romeo, take me somewhere we can be alone / I'll be waiting, all that's left to do is run / You be the prince, and I'll be the princess / It's a love story, baby, just say, 'yes'." This tune was one of the first songs to successfully crossover from country to pop, and become not only the most-downloaded country track in history, but the best-selling country song in the U.S. -- surpassing
LeAnn Rimes' 'How Do I Live?' by 1 million copies.
The first single off his debut album 'Mail on Sunday' the song features
T-Pain, who also co-wrote the song. According to the
RIAA, this top downloaded iTunes song received the highest Gold & Platinum certification of any artist in March of 2008, earning Flo Rida Gold, Platinum, and 3x multi-Platinum prestige for his chart-topping song, which was also ranked No. 3 song on Billboard's
Hot 100 Songs of the Decade.
