Chance Miller, 9to5Mac:

For those unfamiliar, Dolly Parton created a new version of her hit song 9 To 5, cleverly named 5 To 9, as part of a Super Bowl commercial for Squarespace. The country music artist tweeted this evening that if you use Shazam to identify 5 To 9 during the Super Bowl tonight, you’ll unlock a “special surprise” as well as up to 5 free months of Apple Music.

Not sure what the “special surprise” was, but here’s a link to that free 5 months of Apple Music promo. New subscribers only, and it’ll be less than five months if you already have tried a free trial of Apple Music.

I can verify that the five month free trial worked as of this post. If you are interested, best get to it, thinking it will expire at some point.
