Abstract: Techniques and systems for managing audio content for use with a video game playable via a video game system. A graphical user interface (“GUI”) associated with the video game presents visual objects representing audio content in any format aggregated from a number of different sources. Aggregation is achieved by dynamically populating a data structure with data objects configured to store information about various audio sources and audio content stored thereby. The data objects are used to dynamically render the graphical user interface. Via the GUI, a user browses aggregated audio content and selects particular audio content for use with the video game. The data objects and the information stored or referenced thereby (e.g., metadata) may also be used for searching/sorting, translating/transferring, or playing available audio content.
