Despite the title, the movie doesn't particularly feature any goth music or bands. Three bands are listed in the credits. Novocaine Halo is primarily Dark Electronic/Industrial. E-Race is Nu-Metal/Death Metal. And while Abney Park supposedly started as a goth band, it's primarily known as an steampunk band.
The Sidewalks and Skeletons album "White Light", released in 2015, was strongly inspired by the movie Goth. "White Light" refers a designer drug featured in the movie and there is also a song titled "Goth" on the album.
In 2018, a Goth comic book (Goth #1) was published by Blood Scream Comics. Written by Natalie Claude and illustrated by Damien Brunk, the comic is a prequel which explores the character of Goth's origins. Goth writer/director Brad Sykes was a creative consultant on the comic book.
