Weird musicpd + tracks problem

[Frank Staals]

For about a week nog my computer is running Tracks ( 
http://www.rousette.org.uk/projects/ ); a GTD web-application using ruby 
on rails. To play my music I am running musicpd. The weird thing is that 
reloading my tracks page also orders musicpd to play a new song half of 
the times. I don't have a clue what is causing this but it is getting 
more anoying every minute. Does anyone have an idea what could cause 
this behaviour, or knows what I could do to track down what is causing it ?

Some system information:

output from my mpd log when setting log_level to verbose:  ( As shown 
there are no incoming connections from a client )
