<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">First, thanks for the hard work and sorry for us being slow with reviewing. I think the latest patch revisions go into right direction. This turned out be be a serious API designing and code refactoring - a job not usual for a newcomer who's just getting into (sometimes very messy) Amarok code. With this in mind, please don't be disappointed that this goes slower/harder/more labourous than expected.
In this review I've focused on PlaylistFile API, because I took this as an opportunity to clean it up so that it as as easy as possible to use and implement new subclasses. (sorry) :)</pre>

<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">What is the difference between save() and savePlaylist()? Also, if we don't allow constructor w/out url specified, the url arguments here can go away. (which I'd like very much)
It seems that save() is the public method for other code to use and savePlaylist() is the method for subclasses to implement. If this is the case, make it so:
* make save() non-virtual
* make savePlaylist() protected
In each case, both need to be documented.</pre>

Please move to separate .h + .cpp file to make the code more structured. Also, the class and the processTracks() methods should be at least basic purpose description.</pre>

I've started my changes with an implementation of a ASXPlaylist class,
due this work I've found that implementation of different playlist file
types has different logic, as result I end up with a rewriting
playlist's implementations.
As example of difference:
-- Constructor M3UPlaylist::M3UPlaylist( const KUrl &url ) sets a url, but
does not load playlist, therefore loading of playlist are
posponed till data from playlist are actualy needed (lazy loading)
On the other hand constructor XSPFPlaylist::XSPFPlaylist( const
KUrl &url, bool autoAppend ) loads playlist.
The main idea of proposed changes is to create a unify code for
processing playlist files:
-- lazy loading through LazyLoadPlaylist
-- common functionality was moved to PlaylistFile.
It is worth to be noticed that this patch changes structure of
playlist's classes, bit does not changes their behavior, even if this behavior
is inconsistent in some cases.
In following patch-requests I plan to submit ASX Playlist parser and
organize playlists processing in more consistent way.</pre>

2) For all playlists I've also checked loading and
