Research into music press

I have researched different types of music press,  to help me create my music magazine. I found that there was no british branded magazine for the type of publication I would like to create. One of the main magazines I looked at is Top of the pops  this will help me design my magazine this is because I would get a overview on how a professional magazine would look like and create one of my own. 
the different types of music magazines I have been looking at include the following: 

• R&B
• Rock
• Pop
• Rap
