An ideology is a belief and every musical genre has an accompanying ideology. Often genres divide along binary oppositions or a dichotomy. The ideology of the genre affects all aspects of its representation. Music magazines will reflect the ideology of their genres in visual style and language.
Different genres usually talk about different things in songs. For instance, rock music talks about completely different things to pop songs.
Rock includes things such as drugs and alcohol and may have political views. Pop tends to focus upon love, happiness and is usually non-sexual although some things that are mentioned can be thought of as euthemistic.
Rock music is aggressive and loud and the singers usually sound angry or unhappy as they are authentic and making a statement to get their views and feelings across.

Kerrang! music magazine displays popular rock bands on the front cover to gain a wider audience as they know that more people know of them and therefore, are more likely to buy the magazine. The background is dark and the colours used connote aggression and to want to portray an unprofessional appearance to show that they don't care about image although they probably spent the same amount of time putting it together than a Pop magazine. This immediately gives the viewers clear knowledge on what genre the magazine is. According to the National Readership Survey (NRS) more men read Kerrang! than women meaning that the colour theme is more masculine as it tries reaches out to the target audience more so than trying to get everyones attention. Furthermore, they don't want everyones attention because they want to be different and have less of a role model image so thats already losing a typical teenage girl audience.

Kerrang! contents page has a housestyle throughout and is the same in every edition. Just like the front cover, it does appear quite unorganised and chaotic. This is the theme they want though because they need to appeal to rock fans who tend not to like obeying rules. By using images to take up most of the page it makes it look modern and less sophisticated because they have gone against the idea of just listing exactly whats on every page in black and white which represents the 'cool' and 'rebellious' image that they want to connote.
This double page spread of an article in Kerrang! is an interview with Taylor Momsen - an American actress/singer. The background of this page is the same as the front cover - black - which suggests that they want to keep a consistent 'mood' throughout. Rock magazines tend to have interviews with people who are popular at that time and have a 'rebellious' image to appeal to the target audience.

Pop magazines are very different to Rock genres as they need to persuade an audience that the singers within their magazines are good role models. Magazines such as Top of the Pops have people such as Justin Bieber on the front cover because they know that a lot of teenage girls would buy the magazine just because of them. This magazine reflects its ideology clearly by using bright colours and a professional looking layout. The housestyle of the magazine is consistent throughout and the sell line is the same in every edition of the magazine to persuade their target audience to buy it. In this case, it's teenage girls and "the ultimate fan mag" suggests that only the 'biggest' fans buy this magazine and so to prove they are, more teenage girls will buy it increasing sales for the magazine. Also, due to the high demand for singers like Justin Bieber, Top of the Pops are able to have limited edition magazines such as this one displayed because they know the sales will still stay the same if not increase and could even expand the audience as Justin Bieber fans who have never bought Top of the Pops before may decide that they enjoy reading it and continue buying the new editions.

This is a typical Pop genre contents page and it is extremely different to the Rock genre. The layout is simple and easy to understand as the target audience is teenage girls. The housestyle is unique to this particular magazine and each sub-heading helps to indicate which pages have the information relevant to that topic. The bright colours are similar to the front cover and the bold writing all in 'girly' colours portrays the ideology of the genre of magazine and gives a clear view of who the target audience is they are trying to sell to.

This is a double page spread of an interview with Justin Bieber in Top of the Pops magazine. The colour scheme is still a particular house style with a white background so that all the text and images on the page stand out clearly making the whole page look tidy and organised. They are able to use a whole page just for a full body image because they know that enough people will read the magazine because of an interview with him so they can afford to use up a double page spread. Moreover, the magazine tends to include interviews with singers seen as role models so that a younger audience can buy from them. This gives them a wider target audience as parents will allow their children to read it if theres no explicit content.
