Master of None's music supervisor Zach Cowie shares his soundtrack secrets.
How does a hit song end up in a TV show? It's not as simple as it seems.
Every musical moment has to be tested, approved and licensed before it appears on a soundtrack; and that process can take months upon months upon months.
It's all the responsibility of a music supervisor, who plays a critical role in establishing the atmosphere and tone of a series, hand-picking tracks to accompany the action, and getting them cleared for broadcast.
The job has been around for a long time, but there wasn't a "famous" music supervisor until Alexandra Patsavas started working on teen drama The OC.
She gave acts like The Killers, Death Cab For Cutie and Imogen Heap a big break by including their music on the show; and went on to work on Grey's Anatomy, Mad Men and the Twilight series.
Now, shows like Stranger Things, Skins, Girls and The Handmaid's Tale use hit songs as a matter of course. The Emmys recently created a new category for music supervisors, reflecting their increasing importance in the industry.
