Methods and systems for streaming advertising content

One illustrative method for concatenating an unselected content stream (such as advertising) with a selected content stream to create a digital content stream includes interactions between a first server and a second server. The first server can receive a selection of the selected content stream from a hand-held device, transmit the selection to a second server, receive a playlist having location identifiers that identify at least the selected content stream and an unselected content stream, and communicate with a plurality of streaming servers collectively having streaming digital content including the selected and unselected content streams. The first server further communicates to the hand-held device a play time of the streaming digital content, concatenates the streaming digital content from the plurality of streaming servers, and provides the concatenated streaming digital content to the hand-held device as a single content stream.
