Make adding multiple albums from an artist work in the services. This was not possible for several reasons. First of all, the addMatch( AlbumPtr ) function is never called for some reason, messing
up some internal logic, and secondly, the startTrackQuery function is called _after_ the setMatch functions (Which I had expected to be the other way around). It works now, but nicely illustrates
another problem with sorting tracks by track number when inserted into the playlist.
