As the year comes to a close, the trends in music seem to be accurately reflected at the top of the Billboard Hot 100. When you look at the year that was, a handful of artists have had their dominance validated by spots atop the big list, from Ke$ha ("Tik Tok," which opened the year at number one for nine weeks), Rihanna ("Rude Boy," which spent five weeks on top; "What's My Name?" was on top for a week a little while back), Usher (three weeks on top for "OMG") and Eminem (he spent seven weeks at the perch with "Love the Way You Lie"). But the most dominating figure on the Billboard Hot 100 this year has to be Katy Perry, who has sent all three of the singles from her new album Teenage Dream to the number one position. Perry has been steadily building a historic run. "Firework," the current chart-topper, is in its second week on top, while "Teenage Dream" was in first place for two weeks in September and "California Gurls" threatened to dominate the entire summer (it ended up number one for six weeks before being displaced by "Love the Way You Lie"). It's quite possible that Perry could finish up the year on top with "Firework," though Bruno Mars' "Grenade" is making big moves (it jumped two places up to number three this week), as is Enrique Iglesias' "Tonight" (which could make a huge jump from number 15 this week after he debuts the video).
Elsewhere on the chart, T.I.'s "That's All She Wrote" (a collaboration with Eminem) stormed the chart this week at number 18, making it the week's biggest debut. Other debuts included a pair of Christmas songs from "Glee," and way down at number 95 you can find Jamie Foxx and Drake's "Fall For Your Type," a future top 10 smash.
