Introduction-Do rappers on twitter use more non-standard english language than pop stars whether they are male or female?

My hypothesis is, male and female rap artists use non-standard English and Internet slang , whereas pop-stars, male and female use more formal language and politeness.

There hasn't really been studies on the types of language used on social networking. I am looking at the variations of language. My investigation focuses on the different  language celebrities use on the social networking site Twitter. I am comparing tweets from a selection of rappers and pop artists. I am interested to see the difference in politeness and do they act a certain way with their followers/fans on Twitter rather than any other medium?

I have taken into account that rap artists of both genders use informal language and swear, pop stars use more formal language. However this may not be the case, my hypothesis is very stereotypical , who am I too judge somebody just by the music they produce. This is why I want to challenge my judgements, I could be wrong. I came across a article on the Internet (http://www.ugo.com/music/top-11-conscious-rappers) which I found very interesting. This is an important website which shows opinionated on how much rap artists swear.

An physiologist would say swearing is to achieve an certain emotion to release stress, anger, joy or to be surprised. Is swearing too mainstream? What the media thinks, "The mainstream media's been painting the genre with a pretty wide brush, and we think that's, as the kids say, wack" . Rap music/lyrics educate the person who listens to their music or who you are talking to this is overgeneralising a conversation you can have day to day.
I will be looking into lexis and grammar during analysis of the tweets I have collected. Lexically, I will look for Internet slang words, socialect and politeness. I am investigating into the vocabulary of my participants, for grammar I am going to be looking at Abstract nouns, elision, punctuation mistakes and direct questions. Theorists such as Lakoff, Brown and Levinson all challeneged what politeness is. I also think sociolect theorists such as Trudgill and Hudson will help me during my investigation. Peter Trudgill says it's language spoken by a particular social group, class or subculture.It's determinants include gender and age. I'm testing this theory with "particular social group" and linking it to the type of music my chosen artists produce.
