Top 10 BIGGEST songs of the Decade from Hell

So I covered movies already a few weeks ago, and let me specify that these are not my FAVORITE songs of the 2000's, but what I feel are the most popular. I base this on research from Billboard Magazine, airplay throughout the last 10 years, and overall cultural impact. This isn't written in stone, but they are all up there for sure. One thing I will say is that Don't Stop Believing by Journey is probably the most played song over the last decade, but it was released 28 years ago so it doesn't count. I have put together a full list of the top 100, but this is not the forum for that much detail (and most people don't have the attention span.) If you really want that much insight, let me know and I'll email it to ya.

1. Usher- Yeah! (2004) This song could be heard everywhere. Usher was the next Michael...And then he wasn't. Song is still great.
2. Eminem- Lose Yourself (2002) How do you listen to this son and not get jacked up? Best movie theme since Eye of the Tiger from Rocky.
3. Beyonce- Single Ladies (2008) One of the true anthems for this decade. Bachelorette Party's will never be the same.
4. 50 Cent- In Da Club (2003) This movie had everyone from tweens to housewives sayin, "go shawty it's your birthday, we gonna party like its yo birthday."
5. Black Eyed Peas- I Got a Feeling (2009) This song will be heard for years to come everytime a 17 year old girl gets ready for a night out at the movies.
6. Outkast- Hey Ya! (2003) Had biggest catchphrase from a song in the lyrics "shake it like a Polaroid picture." You cannot do that anymore, Polaroid stopped selling the camera 4 years after the song was released. Ouch.
7. Rihanna feat. Jay Z- Umbrella (2007) Before Chris Brown, there was Umbrella. Great track, will not sound dated for many years.
8. Kelly Clarkson- Since U Been Gone (2004) Another anthem. I can tell you there are many, many men who have sang this in their car on the way home from the bars.
9. R. Kelly- Ignition Remix (2004) Great party song. Unfortunately probably will sound dated by 2015.
10. Justin Timberlake- Sexyback (2006) Song took a few listens to warm up to, but American warmed up fast. Sexyback became a pop culture term for the masses.
