Who is the target audience?

The target audience for my magazine is people aged 15-20, both male and female. I have chosen this age group to focus on because I think that people this age are more likely to listen to the music and bands that I am writing about. No one younger or older would probably read a music magazine in this genre, as I am doing research on magazines 'NME' and 'Kerrang!'. Both of which focus on the same type of music. My magazine will be more aimed at females, as the way I write and present it will be in a more feminine way, as a posed to a magazine like 'Kerrang!' where the writing is aimed at males more. Most bands in this genre are all male, so I think that writing in a different style will give a better aspect of females listening to the same music.
