The music streaming service is giving away a free Chromecast to first-time subscribers who take out a three-month subscription.
The deal is valid in the UK and US until February 28, but anyone who has held a premium account in the past does not qualify for the freebie.
Spotify has launched the promotion at a time when TIDAL is shooting up the App Store charts thanks to its exclusivity deal on Kanye West's Life of Pablo.
Meanwhile, Apple Music has emerged as a credible threat to Spotify's dominance, having reached 11 million paying customers in its first year.
