Research - print - target audience

I have decided to create a survey/questionnaire to begin with in order to obtain information based on specific target audiences of different music magazines. This allows me to find a niche market, that may not have been catered to previously, to create my music magazine around in the hope of appealing to them. I originally intended to create a magazine similar to that of NME as it is very popular and, I believe, covers a wide range of music, from the mainstream to newly introduced artists/bands to the slightly obscure. However, this may change once I have attained information from my questionnaire. I have looked at/analysed the front cover of a some magazines and have noted some of the features and conventions that these particular magazine follow. I will then choose one of these magazines to base my magazine on, as a sort of style model. I will base this on the results i gather from my questionnaire and my personal opinion of what i think could work best.
