"I Don't Wanna Live Forever," Taylor Swift and Zayn's soundtrack collaboration for the steamy Fifty Shades Darker, hasn't been an immediate chart knockout for the two pop stars — it's peaked at No. 5 on the Billboard Hot 100 after seven weeks on the chart — but the artists' respective teams seem hellbent on getting to No. 1. On the heels of its music video release, the price for "IDWLF" has been slashed from $1.29 to a mere 0.69 cents on iTunes, which has become a favored tactic of labels attempting to jump start a song's traction. And now, injecting the single with yet momentum, both Taylor and Zayn have casually let separate acoustic versions of "I Don't Wanna Live Forever" hit the internet...just in case you'd have preferred it without the slick production, or even without one of the singers on the original duet.

There's an "IDWLF" version for everybody now, but which do you prefer the most?

Taylor shared a video clip of her rehearsal for this weekend's DIRECTV Super Saturday Night concert, in which she took it back to black-guitar-basics and offered a husky, borderline countrified acoustic version of the track. Meanwhile, as Tay wondered "what is happening to MAY," Zayn shared his own grainy black-and-white video of a strummy and soft take on the song, which offers its own unique sweetness (and plenty of fodder for fans of Zayn's face, unlike most of the darkly-lit "IDWLF" video).

Both versions offer their own rewards, as does the original — but it's time to vote: Which "I Don't Wanna Live Forever" version is your favorite? Listen to all three, and vote below. We'll reveal the winner on February 17.
