<br><br></div>I second that :-)<br><br>As far as adding support for playlists to querymaker, it needs to be done at<br>some point if we're going to (as I thought we were) store playlists in the<br>database in 2.0. This lets us access/modify them much more easily and

I can't check the sources right now, but why not make the PlaylistProvider class asynchronous? Subclasses could then use one or more QueryMaker instances to get the tracks for the playlist (for smart playlists), or download the playlist from the ampache server. Querymaker basically allows us to retrieve tracks from a database (and albums, artists, etc) based on certain criteria. Do we need something similar for playlists. Are we ever going to have a use case "give me all playlists whose name ends with 'foobar' "?
