The song "If 'Screamo' Went Acapella" by Austin Jones is about the challenge of covering heavy metal and screamo songs using only acapella vocals. In the phone conversation heard at the beginning of the song, Austin's friends encourage him to push his limits and experiment with incorporating heavy elements into his acapella project. The lyrics of the song reflect the struggle of attempting to replicate guitar chugs, breakdowns, and aggressive vocals using only vocal harmony and beatboxing. Ultimately, the song is a testament to the power and versatility of acapella music and the creative potential of exploring new sounds and styles.
