Noisy, loud, obnoxious, music which generates hyper activity of any kind is surely not only injurious to the mind and soul but that is also the kind of music which is forbidden in Islam (as per my belief).
Serene, tranquilizing music which generates feelings of welll being, love and peace is not only a kind of therapy of those who need but is also what is NOT forbidden in Islam.
There are various kinds of music creations. It is upto you what you chose to listen to and what your preference is. Obviously if you chose to listen to bad music (which I call noise) for long hours of your precious time during the day or make it an addiction, it will only impair your nervous system (slowly without your knowledge) and harming your faith too.
Most muslims do not make an effort to understand the deeper meaning for any teaching of Quran. They're just like 'lakeer ke fakeer'... what they hear from some mullah and refuse to use their own good brain God gave them for the same purpose. They do not question why. They just close their eyes and think it is a SIN to question or ponder to find the real meaning, purpose and reasons.
