rap 

the word rap i believe is slang for rhyme because thats whats taking place your rhyming consistantly there are other slang words such as rap example, flowing, spittin,mcing ..etc
the fact is its all slang for rhyme it is not a sub-genre of hip-hop

hip-hop is a expression of ones self through ,breakdancing,graffiti,djing and mceeing

rap is slang for a form of poetry rhyme rappers use other forms in there rap such as simile metaphors and so forth

there are different style of rap depending on what the artist is expressing if he is gangster then its gritty and hard so the hip hop beat will be gritty and hard if the artist wants to be upliftng then the beat is uplifting if he wants to be misogynistic the beat will be misogynistic

again this is just what i think rap means

thumbs up thumbs down

Rap 

Poetry with a beat. Usually associated with black people, although not entirely true (see Eminem)

"Its OK to like rap, just because other people don't like it doesn't mean you can't enjoy it. Especially all those people who diss artists like 50 cent and Lil' Wayne. While they may have a point, it doesn't mean it can't be pleasing to your ears"
