Music has nothing to do with sound quality...( But yes sound quality matter for me as for you)
As any musician know...
Jazz or Persian music or classisal or Indian music are all different experience asking something from us: our attention...
We concentrate on something we already knew by our attention focus habit...
We dont concentrate on the "unknown" from which our attention focus deviate ( it is not my taste or my habit)...
The quality of our attention determine the quality of our concentration in a feed back loop...
To increase our attention we must expose ourselves to different music from different cultures...
Then our concentration will increase...
There is no concentration when we listen always the same genre only a body robotic response...
