"Identify" is a song written by Billy Corgan and Mike Garson and performed by Australian singer Natalie Imbruglia for the soundtrack to the film Stigmata.

[3] Billboard reviewer Chuck Taylor described "Identify" as a "moody, dreamlike gem", adding "there's a hint of Portishead here, an inkling of a James Bond theme, and a morsel showing Imbruglia's own growth.

That's not to say that the first half of the album is terrible – there's quite a few good songs there, actually, highlighted by Björk's "All is Full of Love", Afro Celt Sound System & Sinéad O'Connor's "Release," and the Corgan-Garson written and Natalie Imbruglia performance "Identify.

"[5] The music video for "Identify" was directed by Samuel Bayer, known for his clips for Nirvana, Smashing Pumpkins and Garbage and sees Imbruglia performing the song in a dark, broody style cavern, surrounded by ghosts and tombs.

The "Identify" music video is featured as a bonus extra on the Stigmata DVD release.
