There was not any word back.
It was just radio silence.
That was a little bit weird, because so many great people had come forward.
Taylor Swiftactually gave us a song, which I never thought she would do.
I just thought she wouldnt let her voice come out of somebody elses mouth, Safran explains.
The song was really important to me it was Delicate.
But we ended up having to cut the budget, and it got cut.
So theres only one song in that episode.
Safran and his team created all of the mash-ups specifically for the series.
I had no idea how hard that was going to be until I attempted it, he confesses.
The mash-up idea came from its two peoples mix tapes coming together.
I was like, Cool, Ill find two songs and Ill mash them up together.
He would make them.
Then Id have to write a letter to the two artists.
Send the demo of the mash-up.
Theyd have to approve it, and then, we could go forward.
So then Id have to go back to the drawing board and sometimes that process took months.
The series is on Netflix now.
