Whether you like him or not, Calvin Harris is objectively one of the biggest names in dance music today. His albums and music regularly feature on the Billboard Top 100, often peaking at #1, and the company he keeps speaks for itself. Not to mention his ridiculous home that he’s selling for $10,000,000
