I use gmusicbrowser since some years, thanks a lot! Since the upgrade to Linux Mint 16 Cinnamon 32bit, I have the problem that gusicbrowser stops most of the time, but not always playing after each song. No matter if I use the queue or just play by path/album/disk/...order. This happend to my laptop with the same distro, but gmusicbroswer 1.1.10 and my desktop with version 1.1.11 too. I guess this has something to do with mplayer2 (2.0-554-gf63dbad-1ubuntu1), but have no idea for a solution.
Has anybody the same problem and a work around?

Yes there is a bug when using pulseaudio with mplayer2 that makes mplayer2 stop at the end of a file. There is nothing I can do about it from gmb. But you can use gstreamer or mplayer1, or I think using mplayer2 with alsa works even if it goes though pulseaudio.

Thanks a lot Quentin,
As suggested from you, I replaced mplayer2 by  mplayer and everything works fine.
