Sia, Writer of Every Song Ever, has teamed up with Eminem for a contribution to The Equalizer soundtrack. The duo previously collaborated on 'Beautiful Pain', but their perfect chemistry makes sense so they're trying the same formula again.

'Guts Over Fear' is your typical Em rapping about overcoming adversity in his angry voice, and then Sia comes in for the chorus to croon in her warbling voice. For once I'm actually a bit bored by Eminem's rap even though he usually pulls it out.

Sia sounds gorgeous as ever, and she actually gave me goosebumps on this on. I'm starting to think that Sia Furler is some alien from a far away planet that produces musical geniuses because there's no logical explanation for how incredible of an artist she is. If you don't have the time to listen to this song, at least skip to Sia's parts - they're worth it.
