Calvin Harris is one proud boyfriend! He took to social media early Monday morning to congratulate his girlfriend, Taylor Swift, for taking action and prompting Apple to change its payment policy for its streaming service, Apple Music. Taylor published an open letter to the company on Sunday morning, and that night, Apple announced that it'd be shifting course. Following the news, Taylor tweeted her excitement, saying she was "elated and relieved," and soon after, Calvin chimed in with a supportive tweet, writing, "I just played a gig inside a giant owl and my girl just changed the entire music industry what a day." Looks like Taylor can add yet another big win to her year of incredible moments!
