Music Mania: New Releases from Katy Perry, Britney Spears & Miley Cyrus

Another day, another new Katy Perry track. The singer has revealed yet another new track from “Prism.”

In addition to her no. 1 single “Roar” and two non-single tracks, “Dark Horse” and the newly-released “Walking on Air,” Perry performed another new track at the iTunes Festival Monday night.

The song, “By the Grace of God,” is much more somber than what fans are likely used to from the exuberant pop star.

Elsewhere in music, Britney Spears is back with her new single “Work B****,” which debuted at no. 12 on the Billboard Hot 100.

For fans of Brit’s who feel they haven’t seen enough of her lately, they can check out the world premiere of her “Work B*****” music video Tuesday at 9:34pm on the CW, during the second part of network’s two-night telecast of the iHeartRadio Music Festival.

After that, the video will hit VEVO at 9:40pm ET.

Lastly, Miley Cyrus’s full album “Bangerzhas been unleashed on iTunes one week early. The singer released the entire record for streaming, though it still won’t be released until Tuesday, October 8.
