I dug a bit deeper into the media player's working and created new widgets.Now all are inter-related, so you could hit play on the media player and be able to hit pause from the QBW widget!
Also play/pause and play/stop no longer need different widgets.The default action is play/pause, to change it to play/stop change the first line of play widget from
to
As for the not-working-after-reboot problem I found out the cause.The pointer that maintains track of currently selected song gets erased after reboot, so my widgets don't know what to play or what is the next/previous song.How the media player keeps track of this is beyond me so unfortunately no fix for this However it should now require only a single press of play/next/previous in the media player to make the widgets work again.

Set the size of widgets according to your preference and images.The images go in the usual queen beecon directory.

Edit:
All updated again for another fix.Sorry for the inconvenience
Enjoy
