In the article the largest online music hypermarket in Ukraine, the First Music Hypermarket, is analyzed. Peculiarities of the architectonic organization and the content of the music Internet hypermarket are examined. The methods of observation and description were used to form the basic ideas about the topic being studied, analyzed and synthesized in order to comprehensively cover the issue. The site is made in a nice color scheme, the design is modern and concise. Care for the visitor is embodied in their ability to find the desired product in four different ways: three times - by going to the relevant sections of the catalog and once - by specifying the name of the product in the search bar. However, there is no such familiar element as a search filter on the homepage. There are a lot of products and categories, therefore, it would be convenient if the visitor could find the right one, for example, by the manufacturer's name, price, size, as stipulated in the traditional online stores. Filters are only available on the specific product pages. In addition, the lack of the Ukrainian-language content is surprising. Today, this is a direct violation of the Ukrainian Law "On Ensuring the Functioning of the Ukrainian Language as a State one", which states that the main page of the site must be loaded in Ukrainian, and must provide the user with a choice of a language alternative. An attempt was made to analyze the features of the architecture and content of online music stores for the first time. The practical significance of the study is that its results can be used to further explore the concept of "music online store content", to form a scientific study of online resources, create and develop similar online resources.
