Abstract

Methods and apparatus are disclosed for facilitating online storage of files (e.g., audio tracks, video, etc.) for playback/access or sale/exchange by the owners of the files without violating copyrights that copyright holders have in the files. For example, by providing a playback service that does not store additional versions of an audio file when the file is transmitted to, and immediately played on, a user device without buffering, the present invention avoids violating copyright laws by not making copies of the file. Numerous other aspects are disclosed.
