Most of them are related to the new way people do listen to music : often from Spotify, or on some other services, where the playlists are constantly updated and don't have audio files but stream links.</div><div><br></div><div><div><b>Stream sources</b></div><div>There is something to do about the location and the links attribute.</div><div>A track could have some locations (audio files) and links (eg. wikipedia entry), but where should I put stream sources (links to spotify, youtube, apple music, ...) ?</div><div>It looks like they don't fit any category. + sometimes, a stream source is available in one country but not in another.</div><div>Maybe we would need a new attribute here for those stream sources.</div><div>Also, it would be great to be able to set not only URLs for them (files/links/streams), but a title.</div><div>It's a bit weird to display some URLs without knowing what will be opened behind.</div><div>I could have a script that would request every URL to get a title, but well, that would be a lot of requests for a playlist.</div><div>So maybe all those attributes (location/link/stream) could have both an URL and a title. And why not even more...</div></div><div><br></div><div><b>Total tracks</b></div><div>When I fetch a playlist (eg. Spotify API), i will get X tracks back, depending of their API. Spotify has a 100 tracks limit.</div><div>But they do return the number of total tracks.</div><div>So we could have an XSPF playlist that contains 100 tracks but knowing that there is more to load.</div><div><br></div><div><div>4.1.1.2.8 date <br></div><div><i>Creation date (not last-modified date) of the playlist, formatted as a XML schema dateTime. xspf:playlist elements MAY contain exactly one.<br></i></div><div></div><div><br></div><div>The current attribute is for the creation date, but it would be useful to have an <b>updated date</b>. Most playlists now, on Spotify or such, are constantly updated. It would be nice to have their creation time but also their last modified time.</div><div><br></div><div>In the same idea, I would personally like to have an attribute for <b>expiration date</b> (time).</div><div>Why ? My app (for instance) currently loads XSPF playlists and do refresh them every X time. </div><div>A playlist generated from a radio station would refresh after 5 minutes because it contains only 5 tracks. </div><div>But a curated playlist on Spotify would be refreshed every, let's say, 1 day; depending on its activity.</div><div>It would be cool to be able to set an expiry time.</div></div><div><br></div><div>That's all I see for now, what do you think of it ?</div><div><br></div><div>Thanks for your interest.</div><div><br></div><div>Benoît</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">Le ven. 18 sept. 2020 à 01:51, Benoît Gréant <<a href="mailto:gordie.lachance@gmail.com" target="_blank">gordie.lachance@gmail.com</a>> a écrit :<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hi Lucas, <div>First, thanks a lot for your kind reply and interest.</div><div>Maybe the best would be that I take some time to compile all my questions. </div><div>I don't really know how I can help, except by giving some feedback.
