And 2010's Top Musical Artist Is...

Lady Gaga was Billboard’s top new artist last year, and this year she’s moved on to snag the top artist-of-the-year honors. That’s the fastest any woman has moved from one category to the other since Whitney Houston managed the feat in 1985-86. (Chris Brown managed to snag both titles simultaneously, in 2006.) The ranking is determined based on chart performance. So who’s this year’s top new artist? Ke$ha.
