One of the highlights of the uneven but technically marvelous Baby Driver was the soundtrack. Here is Kid Koala's memorably-placed tune "Was He Slow?"
"I tried it on turntables first, mashing all the dialogue bits into it—but it ended up sounding a little too accomplished," San explains. "Like someone who had been spinning for decades—which I have been, but Baby has just started. So I tried it on this magnetic card reader, which was originally made for an elementary school language class. There’s no smooth, elegant, frictionless way to scratch that thing. So when I started trying that it really came out funnier. It made me giggle."
