What kind of institution might distribute your music magazine and why?

The target audience for my music magazine is teenagers/ young adults therefore distributing my magazine in public places like popular supermarkets and/or corner shops, would be a good idea as my magazine could get published widely and would be easy to purchase. To start off by publishing my magazine and selling it through small convenience stores such as local corner shops and maybe some supermarkets like 'Morrisons' or 'Sainsburys', would be a good way to familiarise people with my music magazine. Then, shops such as 'Borders', 'Waterstones' and 'WHSmiths' could be a good way to publicise my music magazine to a much wider audience.
