well, i have a sandisk mp3 player. when i listen to music, in places where theres a lot of people spekaing i like to crank the volume up by a lot, see the thing is that when i go to max volume it isnt that loud, and i see other people with mp3s who goes super loud, i can hear all their music. so is there something wrong with my mp3's volume or the volume depends on the type of file there is? Is it the file that controls the volume? answer wud be appreciated
