I also have this problem, but with gmpc, with a plugin that I had build for it (http://www.gtk-apps.org/content/show.php/gmpc-notify-osd?content=112536). Song info updates sometimes. I tried downgrading to notify-osd-0.9.24 but the problem is the same, but before upgrading to 0.9.25 (I had 0.9.24) all was fine. I think that something with notify-osd-0.9.25 is wrong.
