No trouble - but I am a self taught non-IT person so bear that in mind...

I used QBW and a Mohammed A-G script/app called Phone-Control.

I don't think Phone-Control is a prerequisite, as it seems to be a way to shortcut the more lengthy Phone Control scripts - so MA-G's script lets me write "phone-control --mp-play" instead of the command at http://wiki.maemo.org/Phone_control#...n_media_player (as an example)

Made a new QBW and made the command:
phone-control --mp-play /media/mmc1/sounds/song.mp3 (Note that that this will be the path to the mp3 you want)
Or you could copy and paste from the link above for the long form of the command.

http://wiki.maemo.org/Queen_BeeCon_Widget will give you all the info you need to then setup how your QBW looks, how to make backgrounds/messages hidden if you want

One numpty confession - I chose a song with a single word as a name, because I can't remember how to put in file names with spaces in them...

Anyway - hope you enjoy. QBWs are addictive.
