LISTEN: Bruno Mars Sinks His Teeth into 'Twilight' Single

Bruno Mars’ single centered on the upcoming Twilight film was released on iTunes today – and is already on a rapid descent on the charts! “It Will Rain, written by the half-Puerto Rican singer/songwriter, will be included in the soundtrack of Twilight Saga: Breaking Dawn – Part 1. The highly anticipated film is the penultimate installment in the wildly popular teen vampire saga by author Stephenie Meyer. According to Hollywood Reporter, “It Will Rain” ranked number 14 on iTunes as of this morning – pretty impressive since it was just released!

Bruno Mars Tapped for ‘Breaking Dawn’ Soundtrack

“It Will Rain” brings with it heart-wrenched lyrics (such as “If you ever leave me baby/leave some morphine at my door”) and the soulful voice we’ve come to familiarize Mars with. After watching an unfinished version of Breaking Dawn, the handsome crooner wrote the song, which was also co-produced by his band Smeezingtons. In an interview with Billboard, Mars said he thought it was a perfect fit for the Twilight saga. “The ‘Twilight’ movies for me [are] a love story. But it's a dark love story,” he said. “And I think the best way to describe the song is: It's the darker side of love. I think that pretty much sums it up.”

The soundtrack will be available Nov. 8 and Twilight Saga: Breaking Dawn-Part 1 hits theatres Nov. 18.
