Questionnaire evaluation

I deliberately gave my questionnaire's to people whom are into the rock/metal scene because I knew from the start, that I wanted to create a magazine that celebrates this sort of music.
My results came through with metal with the highest vote, and rock and electronic music came joint second. Using this information I have created a magazine purely based around heavy metal, however there is one or two rock bands featured inside. I also managed to include a electro-heavy metal band in my magazine (as seen on the front cover) so I have satisfied everyone's needs from the questionnaire.
Another interesting thing I found out is that people like to receive free posters in their magazine and it WOULD encourage them to buy a magazine. This is a perfect opportunity to advertise and promote my magazine on the front cover to draw in a bigger target audience, so I will advertise this in my magazines masthead, as it may encourage someone to buy a magazine for the posters, it may not be the idealistic reason I would like someone to buy the magazine, however it will generate more money for the magazine, and the person may be interested in the magazine afterwards. 
My research also found out that on average, for a weekly magazine people would pay £2.50 for a top quality magazine, filling all their needs.
Other information I found out were peoples favorite bands, this was simply so I could include them inside my magazine, to enhance promotion of the magazine, make the magazine look more interesting and invite a wide range of people to buy the magazine.
