Our bus n MRT, now turn into Disco or KTV.
Youngster always like to turn on the volume loud loud, play till whole bus can hear. And then, in the paper, got ppl complain abt air plane fly low n cause noise. I think those who causing noise are those playing back their tunes in the bus/mrt loud loud one. Really some time, want to have a nap also cannot. On top of that, it might distract the driver!
