Lady Gaga's 'Judas' Hits iTunes, Could
Battle Rihanna for No. 1 on Hot 100

The Hot 100's highest debut belongs to Lady Gaga, whose "Judas," the heavily-anticipated second single from "Born This Way" (due May 23), soars in at No. 10.

After being serviced to radio and released to iTunes Friday afternoon (Apr. 15), "Judas" charges onto Digital Songs at No. 4 with 162,000 downloads sold.

By comparison, "Born This Way" began with sales of 448,000 on the Digital Songs chart dated Feb. 26. "Born" was similarly posted to iTunes on a Friday (Feb. 11), although it arrived at the retailer in the early morning (ET), whereas "Judas" hit the online store early Friday afternoon.
