My Original Ideas for a New Music Magazine

I want to make a new magazine which focuses on recording the music charts. I have searched 'Music chart magazines in Britain' and I could not find any results so I may have found a gap in the market. I am hoping to aim to a range of audiences such as professional music producers who like to find out about what is going on in the music industry and also to ages from sixteen who just want to find out about the latest big track. I am looking at having eye-catching colours which stand out, and perhaps have images, fonts and language which is intended for those who are really into the music industry. Currently, I think a mixer would be a suitable cover picture but I may have a change of mind once getting into the production.
