>>2314I have a really hard time believing that the Quran accounted for an entire genre of music spawned from Japanese vocal-synth technology that wouldn't be invented for another millennia. I have an even harder time believing that the Quran knew this would happen, and thus declared it haram.
On a more serious note, most Muslims believe music is all well and good as long as long as it doesn't promote illicit activity. This is still "debated" as to whether or not it's the best interpretation of the Quran (since the Quran makes no mention of music, at all) but some extremely traditionalist groups believe music is totally haram.
As
>>2317 mentioned, beliefs are always followed differently, you don't see many Catholics caring about if the seat they sat on was sat on by a menstruating female in the past week, or many Catholics caring about eating animal fat.
Inshallah the girls shall listen to Miku, alhamdulillah.
