Conventions of existing mastheads for R&B

From searching R&B magazines into google search I discovered the large variety of mastheads that appeared. From the results, I gathered that the typical conventions of the mastheads relate to the music of the magazine and the words are often associated/link to the genre it focusses on. Looking closer at the names of the masthead, such as 'Vibe' and 'XXL', they all have their own deeper meaning that would have been thought about carefully, which are created to capture readers more. The masthead/name appears to be a big factor on magazines as they are one of the first conventions seen by the audience, so with it relating to the music and genre, this would create more of an effect than a random name would have.
