Again another site I found while searching around!
This site provides, amongst other things, rtsp RealAudio .ra and .rm streaming links for BBC Listen Again programs that the you may prefer to listen to (or Listen Again to) from here rather than using the BBC iPlayer. It will let you listen to BBC radio broadcasts on smartphones, Pocket PCs, PDAs, and other mobile devices. It also works on PCs, Macs and pretty much anything else that supports RealAudio, WMA, or Flash.
Very useful 🙂
