Why do rap artists sound so angry?

Because they are

Rap songs that might sound angry probably talks about life situations , killing drugs it adds emotion to the song and draw people in or something could have made them mad and that emotion is coming out in the song. not all rap sounds angry

do no longer push all new artist to the part basically yet. i think of you have had an overload of the mainstream media. get carry of BrookDon's entire album. he's an underground artist that would not glorify promotion drugs or sound asleep around. enable me understand what you think of!!!

Because they're talking about emotional problems and drugs and problems that have happened to them along with the consequences

Its for a tough guy image its certain tracks I sound angry on when I record as well

not all rappers sound angry....that's just stereotyping...like why do all rock bands write about crying about breaking up with their ex gf?

Because life has a way of pissing people off.

thats how they make money
