The SDS Audio player presents can present both audio files and playlists of audio files. The two cases have slightly different display rules. Playlists are discussed first in this document.
What do we mean by 'playlist'?
A playlist is an XML file that contains descriptive and structural metadata about streaming audio delivered from DRS. Streaming audio represented by an audio playlist can contain one or more audio files or/and one or more segments from the same audio file.The XML files use the AES-60 specification and are deposited in the DRS as part of Text Objects. There is more information on creating and depositing playlists in the Creating Text Objects section of the DRS BatchBuilder Guide

SDS playlist information in track listings section
As described in the “Create and deposit audio playlists as text objects” page in the Batch Builder Guide, information for each individual track is stored in <part> ... </part> sections in the AES-60 file.

| Track listing display | AES-60 XML snippet for first track |
 | <part><title><dc:title>1. <-- that number is a part of the title. There is no automatic numbering of the tracks. Also, you can include HTML references in the titles, but you have to encode them. Ever wonder how long titles can be?
