My bat_iplayer script now has a problem.

[batguano999]

Hi
Since the recent changes, my bat_iplayer script is playing up.

Previously, when I used a command like this:-
$ bat_iplayer lo b05wndrq

It would save the programme with a title, like this:-
Shipping_Forecast_-_03_06_2015_b05wndrq_default.m4a

But now it doesn't show the name properly, like this:-
radio_b05wndrq.m4a

Any suggestions how to modify my script (near line 25) to show a descriptive title again ?

It's here ---> http://pastebin.com/raw.php?i=86ue5ETB
