A teenager, or young person who only ever listens to mainstream music, that is usually in the top 40.

As soon as they hear of a band that is not mainstream, they label it as 'an unknown band', and refuse to listen to it.

These people cannot appreciate the art of music, and see it just as something to dance to and talk about with their other little top 40 friends.

The kind of people who only knew who Good Charlotte were, after they sold themselves out and released those pop songs that were massive for a while.

Get the Top 40 kid mug.
An individual that defines their musical tastes on what is currently on the popular Top 40 music charts. Generally considered a mindless pawn to the music industry.
Person 1: How good is this new song.
Person 2: That's not new I heard it ages ago.
Person 1: I just heard it recently.
Person 2: That's because you're a Top 40 whore.

Get the Top 40 whore mug.
The shallow, unimaginative, morons who only listen to top 40 chart music, and live with the weird belief that popularty equals musical talent.

You can spot these complete and utter wankers from a mile away. In America they would usually be Jocks and Preppys, in Britain, they are usually middle class chavs. Generally anybody who follows trends like a religion in order to gain friends, and because they are too stupid to think for themselves.

Whenever a new song (usually some god awfull corporate pop or radio friendly psuedo hip hop) reaches a high possition in the charts, the Top 40 Brigade will play it through their tinny mobile phone speakers for around 2 weeks, after that the song becomes "old", and therefore crap in their eyes.
Top 40 Brigadier: Hey listen to this new song by (insert generic mainstream crap here).

Intelligent person: That is total garbage.

Top 40 Brigadier: Shut up man, it must be good if it got into the top 40.

Intelligent person: Top 40 is nothing but corporate bullshit telling what to think in order to make more money. Now you can continue to listen to that all you want, but im going to listen to some Led Zeppelin.

Top 40 Brigadier: Who the fuck is Led Zeppelin, they sound like some emo band.

Intelligent person: How dare you *punch*, take that you stupid Top 40 brigade cunt.
