I dismiss amarok and rkward for the same reason: a dependency on kde-runtime. This is just a philosophical decision that the kde community made that I disagree with. Why does rkward, a stats program, need to have the phonon-backend-vlc video or libkntlm dependencies? An RDF daemon or kio-audiocd (i don't have a CD drive)? I use awesome as a window manager, so I do not have KDE/GNOME installed. However i can and sometimes will install most "gnome" apps because they do not have a dependency on gnome-core. For comparison:
