It's a Hard Knock Life

I have been studying and researching very closely at the image of Hip Hop artists and groups from dating back to the 80s up until now and I have seen a common similarity about their image and that is that in their pictures they try not to show emotion and if they do it is of anger and this is because Hip Hop music is generally about money, luxuries, violence but there is also a positivity about Hip Hop music and the lyrics which is that they rap about politics, God, life, love, liberation and not conforming to the norm for example Will Smith's Summertime (released in the 90s), a great hit talking about love and enjoy the summer.
