An in-page embeddable platform provides media selection (for inclusion in a playlist or interactive feature) and playlist editing capabilities that may be accessed by a user from a 3rd party web page. The platform allows a web site administrator to present an interactive playlist feature on a web site in manner that is integrated with the characteristics of the web page. Visitors to the web site may customize the playlist dynamically, without leaving the web site. An in-page user interface allows users to select new media, or to re-order or remove media from the playlist directly from the web page. The playlist may be edited or contributed to by any number of users, enabling collaborative media selection. The media-selection capability may be used directly in the context of selecting songs to add to a playlist, or it may be used in a standalone fashion.
