I know some people have a problem where they can't listen to music and read manga at the same time even though they can listen to music and do other things. Supposedly it distracts them from concentrating on the manga. Do you have this problem? I don't at all. Actually the music I listen to usually makes the reading much better. I happen to read a lot of action and supernatural manga and hence my music (mostly rock and metal) goes along perfectly with the manga and I just get even more pumped while reading. It doesn't bother my concentration whatsoever... that might be because I can fall asleep while my speakers are blasting heavy metal but that's another story.
