Let's patent the pop song writing system.
A quick overview of songs by stars Taylor Swift, Ariana Grande, Ellie Goulding and Adele reveals some surprising similarities. In fact, all have songs that are written and produced by Max Martin, a Swedish music producer and songwriter. He has consistently written hits since the Backstreet Boys, and has more number one hits than Michael Jackson. In fact, retaining Max Martin for songwriting is pretty much a guarantee of chart success.
