Lady Gaga’s “Born This Way” keeps getting stronger as it gets older.  The tune remains at No. 1 for a second week on the Billboard Hot 100, gathering strength both in digital sales and radio play.

The title track to LG’s May 23 album sold 509,000 downloads last week, up 14% from its first week, according to Billboard. It also grew in radio play to 84 million audience impressions.

“Born This Way” wasn’t the only tune performed at the Feb. 13 Grammy Awards to show a nice bump:  Cee Lo Green’s “Forget You” jumps 7-2 on the Hot 100, surging 178% in digital sales and 22% in airplay.
