It's Legit!
Gifted myself this for Christmas 2020 and my Spotify Premium expires 3/21/21. I was a bit worried if it would work for me because I saw a review saying someone's code did not work for their previously premium account. I redeemed the code 3/17/21, months after purchase, without any issues. I now have Spotify Premium through 2022! I assume the reviewers who were unable to redeem have the family or student plan! I can confirm it works for the basic Spotify Premium account with or without prior Premium status! Hope this helps!
