I like Arabic music a lot, not just rap but more traditional Debkat and other stuff too. However, Saudi Arabia is not known for musical taste and talents. There is an uneasiness in Saudi Arabia (and even at KAUST) about playing music in the public sphere, because some conservatives believe that music is "idle talk" and would take offense.
So in the KSA there are no public concerts, no music festivals, and not even soft background music in malls and grocery stores... which, if one comes from a musical culture, is really a pretty strange transition. I have heard that in Egypt, Jordan, Syria, Turkey, and Lebanon music remains a part of everyday life - why is KSA different?
The moralist might say that there is lots of "bad" music available, and the public should not be exposed to "bad" music. But it doesn't make sense to hush all music if one thinks that some is bad. Music is one of the most powerful forms of emotional and spiritual expression than man is capable of; when there is a festeval or a wedding, music feels natural. Music makes thoughts, words, and even people, come alive.
I haven't found much in the Quran which references music - either good or bad. Maybe someone who knows more than I can point me in the right direction. There are a few verses about singing praises to God; minaret callers certainly follow these guidelines when they sing the call to prayer.
The Bible (Torah and Injeel) is a bit more clear on the subject of singing. Music is an integral part of the Jewish and Christian religions and traditions. The words sing, song, and music appear 188, 115, and 106 times in the Bible - almost all in positive contexts.
I love music, and even if I can't go to a public concert right now, I will keep singing until the day that I die. Life is too good to stay silent.
