Apostate prophet shares his musical tastes; inappropriate Adhan?

In answer to the video "The Annoying and Offensive Adhan"

Before talking music, it is interesting to note that the adhan actually is a prophecy realized. The Quran addressed the prophet in no uncertain terms, telling him in a prophecy that this city of Mecca ruled by a powerful people who had just expelled him and his followers from it 47:13,50:36 will become the centre to which men will come for pilgrimage and for the devotion of the One God 22:25-7. He and his followers will see the realization of that prophecy in their lifetime. That powerful nation will be uprooted and cut off from God's mercy although the current state of affairs was indicative of the contrary, that the opponents will instead succeed in cutting him off 108:3. 

Prophecies continued coming speaking of their abasement as the rejectors in the nations of old were abased 58:5 while the Believers are exalted 47:1-5,54:45-6 and bound to be victorious 47:35. The prophet is told that such an outcome will be witnessed in his lifetime, with the entering of the people like waves upon waves into the religion 110:1-3. And above that, Muhammad is told that despite these calumnies he will be dignified 94:4. The elevation of the prophet's remembrance besides having initiated in his own life is an ongoing, virtually unceasing exponential worldwide phenomenon. It occurs when the time of adhan followed by one of the timed prayers arrives, and does so continuously a few minutes later in a close-by location and by a certain point, the cycle starts again for another prayer at the origin.

The adhan addresses only the Muslims within the vicinity of a mosque. It invites them to gather at the edifice for prayer, while restating certain cardinal pillars of their own beliefs. If certain non Muslims feel offended by these declarations when they hear it, then it is due to their own complex towards something that neither concerns them nor should be within the reach of their hearing to the point it would disturb them. As a side note, mostly those who see the adhan as an aggression already hate Islam itself as a religion, to the point that whenever they come across anything reminding them of it, whether the adhan or else

17:41,89"And certainly We have repeated (warnings) in this Quran that they may be mindful, but it does not add save to their aversion".

In terms of noise pollution, certain calls to prayer may be annoying to hear to anyone, including Muslims. This could be due to the unpleasant voice of the caller, the volume of his pitch or even defective sound systems. But this is a problem of modern times, especially in areas counting several mosques close by, each having loudspeakers. Traditionally, the caller to prayer would summon the people from the minaret, the roof of the mosque, or on the street outside of it, using only his own voice and for 2minutes at most. This means his call would mainly reach the ears of Muslims who lived in the neighborhood of a mosque. Just as with any religious community, in pre-modern times the people of each religion lived close to their respective religious constructions. That is why the scholars say that a Muslim is only bound to attend the congregational prayer at the mosque if he hears the adhan in a regular voice with no amplification device. A Muslim is not obligated to run to a mosque 5kms away, even if he hears the blast of its loudspeakers. Even for those living close by, they shouldnt come with haste but

"with calmness, and pray whatever you get (with the people) and complete the rest which you have missed".

And if external conditions make it difficult for them to reach the mosque they can as well pray in their homes 

"On a rainy day Ibn `Abbas said to his Mu'adh-dhin, "After saying, 'Ash-hadu anna Muhammadan Rasulullah' (I testify that Muhammad is Allah's Messenger), do not say 'Haiya 'Alas-Salat' (come for the prayer) but say 'Pray in your houses'." (The man did so). But the people disliked it. Ibn `Abbas said, "It was done by one who was much better than I (i.e. the Prophet (p.b.u.h) ). No doubt, the Jumua prayer is compulsory but I dislike to put you to task by bringing you out walking in mud and slush".

A mosque thus is not supposed to attract those living far from it, only those that are within a close walking distance so much so that they may reach it without rushing. This further highlights the inappropriateness of having loudspeakers broadcasting the adhan. That is also why the mosques would only be built within essentially Muslim neighborhoods, and at the majority request of the residents. Non Muslims who feel offended by the adhan are not obligated to live within the precincts of a mosque where the natural sound of the caller can be heard. This means that at most, a non Muslim should only hear a faint distant and unintelligible sound when the adhan comes. Today, Each Islamic community and nation worldwide has its own legislation in regards to public noises, which include the adhan that has become part of the problem in some places due to modern developments.

The words of the adhan came through inspiration. Either to the prophet directly as per certain ahadith or to a companion in a dream who then reported it to the prophet

"When morning came, I went to the Messenger of Allaah and told him what I had seen. He said, “This is a true dream, in sha Allaah".

A "true dream" is one that may be experienced by anyone other than a prophet and is considered divinely inspired. The repetitions in the adhan are meant at negating an implied falsehood, then affirming a truth.
