This should be fixed now.

Tried the latest Cog Version 2846 (2846-gf52de150). If I hit Command-Right 2 times in a row it works (although the play icon jumps around a bit in the list). If I press it 4-5 or more times quickly, it enters a state where and all songs fail to play and advance to the next song every few seconds (either immediately, or playback stops and this error occurs when I resume playback). One time Cog beachballed instead.

(I'm mostly using mpd on a spare laptop hooked up to room speakers, with game audio files pre-converted to .flac, to play music now. But I can still test this bug to see if it's fixed.)
