Cause people like it. It's lyrically complex, uses interesting beats, builds on other very popular genres. What exactly are you asking? Rap has been popular for decades. It's not really that old of a genre in the grand scheme of music and it didn't take very long for it to catch on. As the internet and such as made music easier to obtain and listen to it's going to spread more and more.

I try to give everything a chance at least once, in case I might find something good.

"Music makes me forget myself, my real position; it transports me to some other position not my own. Under the influence of music it seems to me that I feel what I do not really feel, that I understand what I do not understand, that I can do what I cannot do. I explain it by the fact that music acts like yawning, like laughter: I am not sleepy, but I yawn when I see someone yawning; there is nothing for me to laugh at, but I laugh when I hear people laughing.... Music carries me immediately and directly into the mental condition of the man who composed it. My soul merges with his and together with him I pass from one condition into another, but why this happens I don't know."
