I understand and thats exactly why i wanted to reply to you, because what works for some doesnt work for others and vice-versa
I personally agree with Sammy that the music is the energy carrier so it is still needed some of it not at zero.
And its not even that is a subconscious thing i need to hear it because i have used them a lot of times with cell phone in my pants pocket where… i cant hear and they work. Also i have to use headphones at work when talking to long distance clients and the volume is very low so i dont hear them but i know my aura is absorbing.
But how is a field going to work if the volume is at zero so its not coming out through the speaker?
If it has worked for you great!
But ill stick to what works for me 
At the same time, just like you pointed out that we need to be careful what we said to not confuse others, your approach has not been stated by Dreamweaver or Sammy and that can also get confusing for those who may follow then come and complain here that the fields dont work when its you that probably has a higher connection to fields and stuff that others dont have.
