We spent a whole hour and a half lesson searching through music websites such as Freeplaymusic.com and Bensound.com. We were unsuccessful, we could not find any music that matched the pace and genre. Everything we heard was either too classical or upbeat.
We finally found audio to fit our opening on incompetech.com, it's called Bump in the night. Here it is.
We chose this piece of music because of the screeching sounds and the drum in the background.
