"Most people wouldn't know music if it came up and bit them on the ass"

In this quote, Frank Zappa is expressing his belief that many individuals are not really well-informed about music. He uses a humorous and overstated metaphor of music "biting them on the ass" to stress his point. Zappa recommends that the majority of people do not have a deep understanding or gratitude for music, and that they would not acknowledge its worth even if it existed to them in a forceful or apparent way. This quote might also be interpreted as a commentary on the absence of attention and gratitude given to music in society, and the need for individuals to be more open-minded and educated about different types of music.
