In the early days you could get the summary of The Archers episodes for the week in advance by twiddling the URL.... At some point they got wise to it, and they might get wise to this too.
The much-missed Beeb-O-Tron[0] used to have a function to do this called the "Beebobodge"[1], given any timeslot in the week. Nowadays I use Radiofeeds[2] to get live URL stream links which I play through Transmission on Android or VLC on PC.
