Music is clearly prohibited as mentioned by the hadith below, you don't even need scholar's fatwas to know this much. Any nasheeds accompanied by Music is also in the same category. Putting an Islamic spin on it doesn't make it any more halal. This goes for all "islamic" singers out there who use music. Only instrument allowed in Islam is the duff/daff , a one sided drum. That too was for the purpose of either war, call people for important announcement or special events, such as eid and weddings in which cases usually the the past time was with the women and children. Today scholars says nasheeds with music not allowed but with daff is ok. Only thing of advice then given in this matter is that one does not busy themselves with this so much as to neglect their religious and other duties.
Messenger of Allaah (peace and blessings of Allaah be upon him) said:
"There will be people of my Community who will hold fornication, silk, wine, and musical instruments to be lawful'' (Bukhaari)
This hadeeth indicates in two ways that musical instruments and enjoyment of listening to music are haraam. The first is the fact that the Prophet (peace and blessings of Allaah be upon him) said: “[they] permit” which clearly indicates that the things mentioned, including musical instruments, are haraam according to sharee’ah, but those people will permit them. The second is the fact that musical instruments are mentioned alongside things which are definitely known to be haraam, i.e., zinaa and alcohol: if they (musical instruments) were not haraam, why would they be mentioned alongside these things? (adapted from al-Silsilah al-Saheehah by al-Albaani, 1/140-141)
Women are more affected by songs, musical tunes and the meanings of their words than any one else. Listening to songs may lead a girl to fall in love with the singer, to the degree that his songs and pictures are never far away from her mind.Songs cultivate hypocrisy in one's heart just like grains grow and thrive in the presence of water, as Ibn Mas`ood said. Songs and Qur'aan can never co-exist in a believer's heart because of their contradictory nature. The Qur'aan enjoins us not to follow our lusts, or the footsteps of Satan and to stick, instead, to virtuousness. As for songs, they invite us to the opposite.
Messenger of Allah (Allah bless him & give him peace) said: “Song makes hypocrisy grow in the heart as water does herbage” (Sunan al-Bayhaqi).
