Target Audience

As my magazine is an alternative genre my target audience will be young mature music lovers (16-25 years old). I think this is a perfect target audience as these are the ages where they are able to buy the magazine without having to worry about cost. From  the age of 16, people will start to become more interested in a wider range music and different genres than they listened to below 16 years old.
My target audience is similar to Mojo Magazine. They describe their audience as:

     "Discerning and passionate music aficionados, the MOJO audience is predominately male (72%) and affluent (36% AB). These heavy consumers of music see their passion as discovery without boundaries, genre and decade being secondary to quality."

I am going to be reviewing a few Mojo magazines so i can get a good idea of what their conventions are and an idea to help with mine.
