Musical Hegemony and the Billboard Music Charts

The Billboard Music Chart, a music publication which dates back to the year 1894, has been releasing a weekly ranking of songs in the United States. Its online counterpart Billboard.com has archived lists of songs which made it to the Hot 100 dating back to 1958. Currently, it releases ranking of songs according to the following categories and genres: Hot 100, Billboard 200, Pop, Breaking and Entering, Rock, R&B and Hip-hop, Country, Latin, Dance and Electronic, Christian and Gospel, Additional Genres (such as Youtube), and international rankings for Canada, France, Germany, Japan and Korea.
The Billboard Music Charts has been ranking songs since the late 1800's, which means it has been changing the music scene and dictating taste to its audience, primarily Americans, since that time. Making it to the Billboard Music Charts would mean more sales for an artist, while the failure to do so would mean lower sales, fewer audience and marginalization. This would make the Billboard Music Charts the most influential mass medium that dictates such success or failure in the music industry.
Personally, media organizations which claim authority over certain markets do not appeal to me. These organizations, such as the Billboard Music Charts for the music industry, can affect how the masses think through rankings of songs, for example, depending on that organization's views. It is prone to abuse by people who seek control over a particular market. When such a system is corrupted, for example, singers, artists or their corporations could merely pay a certain media organization to positively rank their products or show them to be in a good light. Doing so would yield a wider audience and more sales for that product. Such media organizations also create a hegemony by making a large number of people think in the same way, as in dictating music tastes. People who don't like the songs on the Billboard Music Chart rankings, for example, are socially excluded and are either forced to think how the vast majority would or are entirely shut out socially. These are the effects of such charts, they dominate and force a certain belief, or in the case of the Billboard Music Charts, a certain type of musical taste into the masses, thus changing a particular culture.
