Knowing that jobs at record companies had become scarce as the music industry constricted in the post-Napster era, he registered at an employment agency that placed temps at labels.

He was assigned a short-term job at Interscope, and was quickly hired as a full-time assistant to Martin Kierszenbaum, then the head of international marketing for the label.

[6] Over the course of his ten years at Atlantic, Bay-Schuck worked with Cee Lo Green, B.o.B., T.I., Trey Songz, Travie McCoy, and Trick Daddy, among others.

[11] At IGA he worked with artists including Gwen Stefani, Imagine Dragons, Lady Gaga, Skylar Grey, Maroon 5, OneRepublic, and Selena Gomez.

[8][13] He said that increasing the focus on pop and hip hop artists were among his goals as Warner's CEO; since then, the label has had #1 hits with Saweetie featuring Doja Cat ("Best Friend"), Dua Lipa ("Levitating") and Bebe Rexha ("Meant to Be"); and signed artists including Zach Bryan, Teddy Swims, NLE Choppa, Benson Boone, Veeze, and Omar Apollo.
