Well, they aren't all like that, but there's a familiar enough sound to the account.

"...nobody was really listening to the music" - clearly the people playing the music are counted as "nobody" to the lad - who also seems to find it hard to understand that listening to the music doesn't have to mean that you have to stop doing other stuff at the same time and sit down and behave yourself. Or the wit to appreciate that this is just one part of what is going on.
