Just updated to the latest CVS, time reporting is broken again in
GstPlay- should I file a bug or just let it be for now as its CVS
anyway? Otherwise, mp3 playback seems to work perfectly now ..

It seems to matter a bit indeed. With alsasink a song switch can take up
to 2 seconds, osssink (on alsa oss emulation) is a bit faster (takes
around a second usually).
