The patch v12 works rather well here, just one minor problem I've faced - if I drag a playlist from File Browser to play queue (the "main" playlist), the track order is not preserved. Could you please have a look at it? Perhaps it is better to query all tracks at once after trackLoaded() is called instead of using trackAdded() method.

When I tried to build it with -DKDE4_BUILD_TESTS=ON, build failed because of undefined reference to symbol 'ThreadWeaver::Weaver::instance()' in testmetamultitrack. It happened because ${KDE4_THREADWEAVER_LIBRARIES} was not added as link library for testmetamultitrack.

Oh, please fix that link error. It is strange but known that something on my box links ThreadWeaver even though I don't explicitly mention it, which then causes build failures on other boxes.
