Hi experts out there.

Got a weird thing happening when playing music via my Blackberry Torch.

If the backlight has gone out whilst playing music from a playlist or even the all songs lists - it will not play the next song automatically.
This only appears to happen to songs with the properties labelled 3GP????

The odd thing is - is that if the backlight remains on or I am doing something else with the phone so the screen is lit - I do appear to have this issue.

Is this something to do with the file format or the BB backlight - or perhaps both!!!

Help appreciated.
