Reducing delays when moving from one track to another

[the_bertrum]

In my experience the MPD pre-fetch doesn't actually work. Rather then getting track ahead of playback until the cache is full, it gets tracks as they start to play just the same as normal, but just leaves played ones in the cache until it's full. Almost exactly the opposite of what it needs to do. I confess I've not tried it on the more recent versions of MPD, it was probably a year ago I last looked.
