This site Islamqa.com looks really interesting. It's all the islamic fatwas. Wiki: A fatwā in the Islamic faith is a nonbinding but authoritative legal opinion or learned interpretation that the Sheikhul Islam, a qualified jurist or mufti, can give on issues pertaining to the Islamic law. The person who issues a fatwā is called, in that respect, a mufti
If you're ever curious about how a Muslim is supposed to react to particular situations, this is a great tool to understand the tenets therein. The site is in Arabic but google translates it well. Then just enter in question. that's all. I decided to poke around and there's a fountain of information there. I tried "western music" to see what results came back. Here was the response to someone who couldn't give up classical music:
1 – With regard to music:
It is forbidden and is not permissible to play musical instruments or listen to songs and tunes. The majority of scholars say that it is haraam, including the four imams of fiqh: Abu Haneefah, Maalik, al-Shaafa’i and Ahmad (may Allaah have mercy on them all).
The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Among my ummah there will be people who will regard as permissible adultery, silk, alcohol and musical instruments.” Narrated by al-Bukhaari (5590). See also: al-Silsilah al-Saheehah by al-Albaani (91).
It goes on for quite a length after that...

Shaykh al-Islam Ibn Taymiyah (may Allaah have mercy on him) said:
This hadeeth indicates that musical instruments are haraam; this includes all types of instruments.
Majmoo’ al-Fataawa (11/535).
But then I typed the word "murder" and I'm a bit concerned to what I found. A man writes in and admits to murder. This was the question: "I took part in a murder, but I was not caught for this crime. I want to expiate for my sin. Will Allaah accept my repentance without me having to hand myself in to the police?"
And here was the response:
Murder (killing a person deliberately), if the victim is a believer, is one of the greatest of major sins, because Allaah says (interpretation of the meaning):
“And whoever kills a believer intentionally, his recompense is Hell to abide therein; and the Wrath and the Curse of Allaah are upon him, and a great punishment is prepared for him”
[al-Nisaa’ 493]
And it was narrated that the Prophet (peace and blessings of Allaah be upon him) said:
“A man will continue to be sound in his religion so long as he does not shed blood which it is forbidden to shed.”
If you killed a believer deliberately, then there are three rights which are connected to that: the rights of Allaah, the rights of the victim and the rights of the victim’s next of kin.
With regard to the rights of Allaah: if you repent sincerely to your Lord, then Allaah will accept your repentance, because He says (interpretation of the meaning):
“Say: “O ‘Ibaadi (My slaves) who have transgressed against themselves (by committing evil deeds and sins)! Despair not of the Mercy of Allaah, verily, Allaah forgives all sins. Truly, He is Oft-Forgiving, Most Merciful” [al-Zumar 39:53]
With regard to the rights of the victim, he is not alive so you cannot put things right with him. The matter has to wait until the Day of Resurrection, i.e., the settling of scores with you on behalf of the victim will take place on the Day of Resurrection. But I hope that if your repentance is correct and is accepted by Allaah, then Allaah will compensate the victim with what He wills of His bounty until he is satisfied, and you will be reprieved.
With regard to the rights of the victim’s next of kin, which is the third right, you cannot be absolved of this until you hand yourself over to them. Therefore you have to hand yourself over to the victim’s next of kin, and tell them that you are the one who killed him, then they have the choice. If they want to they can exact vengeance upon you, if the conditions of qasaas are met; or if they want to they may take the diyah (blood money) from you; or if they want to they can forgive you.
Not anywhere in there does he mention non-believer. The entire response was predicated on murdering a "believer" so therefore, killing a non-believer wouldn't be murder. Despite the fact that murder is murder and all he needs to do is pay off the family is disconcerting.
What say you?
