Taylor Swift is one very lucky singer. In heartbreak and in success, money comes gushing into her bank accounts. You may ask how? Her song inspired and about her ex-boyfriend Calvin Harris is making waves on air.

"This Is What You Came For" topped the summer chart. The song was penned by her before their messy break-up. Did the split drama helped propel the song to the top? Possibly, yes!

How can a song make the writer a millionaire? As verified by a Teen Vogue source, a song that landed on the Billboard 100 top five means a $500,000 income for the songwriter. Since Taylor Swift is the writer and at the same time owns the partial publishing rights to the song, it explains how.

Tom Hiddleston's ex-girlfriend also wrote "Better Man" for country band Little Big Town. It the song hits also, she has surpassed the $1 million mark.

Has the Calvin Harris break-up helped toss up the sales of the song? It is vaguely known but considering the lyrics, it must have been the secret. Has Tom Hiddleston contributed a bit? Possibly so, he added drama to the break-up.

It must have been lady luck smiling at Taylor Swift. The split happened almost in time for "This Is What You Came For" release.

This year, the "Bad Blood" singer won 10 Grammy awards. It is not impossible for her to top the Forbes list of the highest-paid singers again.

Meanwhile, there is another feather in the cap of the "Shake it Off" singer. She is featured in a new all-about-her channel by AT&T. Interestingly; it will be solely for the videos, behind-the-scenes footage, concerts and more from the singer's archives. It will be part of the network's DirecTV Now streaming service.  

Taylor Swift does not run out of things to do on stage and on television. That is why; she has no time to lament about broken hearts. Check out more fresh news from the music industry.
