why RAP?

Today music plays an important part in one's life. There are dozens of genres than evolve out of music.

BUT WHY RAP?
What i personally feel is that other genres make you feel good but they don't mean anything or they are less meaningful. For example if a pop singer says that he/she is in love, a rapper would give us the reason why he is in love and what he feels when in love all that in the same fraction of time.In short a rapper can express a lot more than any one else. Whenever i felt low or at the times when i was in joy all i did was that i cherished every single verse of a rap song and i related it to my life. YEAH! Today Rap is my life!!
So if want to be a rapper then rap and not blood should flow through your veins!
