LOS ANGELES  - Lady Gaga's "Born This Way" led Billboard's Digital Songs chart for a second week on Wednesday, one of many tunes to enjoy a Grammy-related sales boost.

The song, which the pop singer performed at the February 13 ceremony after hatching from an egg, shifted 509,000 copies during the week ended Sunday, a 14% increase.

It's the fourth-largest week for a digital download, and it's just the fifth song to shift more than 500,000 in a week. "Born" is also the first No. 1-debuting song to post a sales increase in its second week since Beyonce's "Single Ladies (Put a Ring on It)" in December 2008.

Elsewhere, Grammys performer and winner Cee Lo Green rose four places to No. 2 with "F*** You (Forget You)" (412,000; up 178%), while "I Need a Doctor" by Dr. Dre featuring Eminem and Skylar Grey soared nine places to No. 3 with 283,000 (up 172%).

Justin Bieber's "Never Say Never" jumped eight to No. 4 (199,000; up 67%), and Bruno Mars' "Grenade" moved up three to No. 5 (180,000; up 25%).

Rihanna's "S&M" edged up one to No. 6, Katy Perry's "Firework" dropped five to No. 7, and Pink's "F**kin' Perfect" was also down five, to No. 8. Wiz Khalifa's "Black and Yellow" fell four to No. 9, and Avril Lavigne's "What the Hell" rose one to No. 10.
