Pharrell Williams' monster hit "Happy" is about to take on yet another life -- as a lullaby.
A baby-friendly remake of the song, which hit No. 1 on the Billboard Hot 100 and has sold more than four million copies, will be featured on "Good Baby, Bad Baby," the latest release in the popular Rockabye Baby series, which creates lullaby versions of pop, rock and rap songs.
The set comes out on June 25 and also features versions of Beyonce's "Halo," Gnarls Barkley's "Crazy," Maroon 5's "She Will Be Loved" and Radiohead's "Creep," along with nine other tracks and a picture book.
Rockabye Baby executive producer Lisa Roth tells us that "Happy" was "actually added on at the very end" of the project:
"It was just a no-brainer for 'Good Baby,' and as we were producing the CD and the cover art and the blurbs and the music that song was blowing up bigger and bigger and bigger and bigger, and I finally said, 'We have to add that.' It's such a happy song and this is such a funny, fun, happy compilation/picture book, it was a no-brainer."
"Happy" originally appeared on the soundtrack for "Despicable Me 2" and is on Williams' latest album "G.I.R.L." It was nominated for Best Original Song at the 86th Academy Awards.
Williams, meanwhile, is nominated for Top R&B Artist at this year's Billboard Music Awards, taking place Sunday (May 18) in Las Vegas, and also shares nominations for his collaborative role on Robin Thicke's hit "Blurred Lines."
