I dont know y some people like to blast their mp3 using
loudspeaker in the MRT?
Is it because their earphones are not working, or they are trying
to promote the song?
I suggest that those who like to do that to be cooperative. Some of
the passengers in the MRT are tired, especially going home from
work. They need peace and quiet. Also, not all of them like the
song played, can be irritating sometimes.
