Squeezebox med serv, prem sptyf acc-playlist and tracks avail on sqzbxmedserv but wont play

All linked up well today however the tracks the the 7.7.2 squeezebox media server can see within spotify wont actually play.  They will play for 4 seconds max within the media server software (but no audio output) and then stop, sometimes it goes onto the next track but only 2 or 3 times and the same thing happens, then it just stops.
