Initial Ideas: Genre/Target Audience

For my main task I had to decide on what genre of music my magazine was going to fit into. I decided on the Indie/Rock genres as it seems to be very popular in the current climate. After this I had to look into what audience i was going to target, i decided on music fans of both sexes aged 13 to 30. I choose this because it gives me both a broad and niche target audeinces in which i can use to my advantage.
