A brand new track by Lady Gaga has surfaced online, Digital Spy reports.

The star has recorded new cut 'Till It Happens to You' for upcoming documentary The Hunting Ground, which is released in the U.S. today (February 27).

A low quality recording of the track has since appeared on the internet.

Gaga co-wrote the track with legendary songwriter Diane Warren, with the subject matter reflecting the documentary's look at the lives of young people affected by rape.

"Till It happens to you, you don't know how it feels," Gaga tweeted last month, referring to the song's lyrics.

Gaga recently opened up further about the abuse she experienced as a teenager.

"I don't want to be defined by it," she said. "I'll be damned if somebody is going to say that every creatively intelligent thing that I ever did is all boiled down to one d**khead that did that to me.

"It wasn't until I was a little bit older that I went, 'Wow, that was really messed up... You were 20 years older than me. I was a kid.'"
