Recitation and Listening to the Quraan

Listening to tilaawat on one's headphones when music is being played in a gym

Q: If music is being played somewhere and a person doesn't want to listen to the music and he plays tilawat in his headphones to avoid the sound of the music, is it a correct thing if he has no authority to stop that music?

I go to the gym and they play music there. So I listen to tilawat in a loud voice in my headphones to avoid the music. Is it a correct thing ?

Reciting Quraan while other passengers are listening to music when travelling

Q: I travel quite early to work and I travel with other people. I try to recite Quraan after fajr, that means I am travelling to work at that time. In my transport the people listen to music. I want to recite Quraan. Can I read even though there is music playing in the background? May Allah Ta'ala protect us.

Secondly, should they recite these surahs mentioned in the hadeeth on regular basis.

Not wishing to listen to the Quraan before an exam

Q: Is it sinful to not want to listen to the Quran right before an exam because you fear that listening to it might cause you to forget some of the stuff you are trying to memorize for the exam? Would it take one outside of Islam to think that the Quran could cause any sort of harm? Obviously, harm can only occur with the permission of Allah, but I mean thinking that the reason for the harm could be the Quran?
