Hi I wonder if you got anywhere with this?

I download programmes like Folk Club (Radio Ulster), Travelling Folk (Radio Scotland), Celtic Heartbeat (Radio wales) using free software called radio downloader. I then use an SD card to get these to my car to listen to, however its a pain to have to listen to two or three tracks you cant stand becasue to jump to the next track takes you to the next radio programme. Has anyone managed to put breaks in these tracks? Ideally say every minute and the ability to do a batch of say 20 radio programmes at once.
