Music is not a universal language for all.
The classical music perhaps could unite all the nations in Europe than any major language. That, however, can not guarantee the people in any other parts of the world can communicate by same types of music. How could the taste for music be cultivated?
Our likes and dislikes of the particular sound is nurtured by the community we are in. Just of the calls for prayer appeal to people in the Middle East, just as J. S. Bach's cantata appeals to the people in Europe, the inherent meaning of the sound affects our tastes for music.
That is, not all of us share the taste of music. "I want to go to a party!" screams a rock star, and that might give you a headache. The drum beat from upstairs might anger you a lot more than Stravinsky's the Rite of Spring.
Just as what is termed as the sense of humor differs in each religion, music can be perceived in many different ways. Granted that abstract concepts are only possible for highly sophisticated minds, the innocent assumption of certain types of equality, however, often only regarded as arrogance.
