Research and planning: Initial idea for music magazine

My initial idea for my as media music magazine will include different subgenre's of music and also distinct genres such as classic rock, rock, blues, grunge and metal. This could be called an alternative interesting magazine as it includes styles which are quite dissimilar. My intended target audience is men and women from ages 20-35, as they are more likely to buy music magazines. The music magazines I have researched have influenced my potential idea because they have shown that many different styles of music can be included in a magazine, therefore I am able to mix together lots of styles of music.
