Ideology

Ideology is important throughout a music magazine because it distinguishes who the target audience is.

For Example:

 In this Top of the Pops magazine you can easily distinguish that its for little girls that have a 'Crush' on the latest teen pop sensation, it also says in block letters 'World Exclusive BATTLE of the FITTEST' The magazine publisher has used teen slang such as 'fit' to make it more interesting for the young reader.

My second example is an NME magazine:

On the other hand this magazine cover is completely different to the top of the pops magazine and will appear differently to different age groups. On the front of this magazine you could say it is more formal because it says 'ARCTIC MONKEYS on the third album that changed them' instead of  'World Exclusive BATTLE of the FITTEST'

 

These two examples show how important ideology is in Music Magazines because without using your sense of ideology the magazine wont appeal to the target audience you are looking for.
