Listening to http://www.bbc.co.uk/programmes/b050rjwr (from about 6mins 
in) the solo singing does definitely have audio problems.

What initially threw me off was that piece of music is clearly a dodgy 
transfer from whatever it was originally recorded to -- possibly 
transferred from tape; there's midrange distortion, excessive background 
his and some weird phasing which isn't present in the Presenter 
microphone when she talks. It may just be a poor quality source file for 
the song.

Picking another random point - 22:00, I started listening and 
everything sounded fine for about five minutes, then I heard more 
pops...

... Then as I wrote another email, I listened to both the MP3 and AAC 
Radio 3 on-demand streams, and sadly they're replete with audio 
glitches. I'll see what I can do.

If people have examples of other on-demand programmes with obvious 
audio problems, please pass them on.
