Processed Sounds that Resemble Music

Question:
now-a-days, acapella singers are gaining popularity. they make background music using vocal only. they slightly distort original sound using computer software so that it sounds almost like original instruments. but often, it becomes unbelievable that, it's a vocal only song. is it haram to hear these songs? they are not, are they? well, muslim singers like rhamzan days, maher zain, khalid siddique don't use higher degrees of digital effect.
Answer:
All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad 
is His slave and Messenger.
We clarified in previous Fataawa that the sounds that resemble music to the extent that the listener would not be able to distinguish whether or not it is music, and human voices that are processed by computers until it becomes similar to music; all these take the same ruling as music and one is not allowed to listen to them.
In Islam, there is no difference in ruling between things that are similar, and on the other hand, Islam does not give the same ruling to two contradicting matters.
Since you communicate with us in Arabic sometimes, then will refer you to the following Fataawa on our Arabic site: 126334, 212719, 257551, 159247, 125271, 318979.
Allah knows best.
