iRecordMusic is a handy little app that I use at least once a week. It did cost me about $15 for a licence, but it’s well worth it. Basically you can record streaming audio from web pages and internet radio streams. It only records in real-time, so if something lasts an hour it’ll take that long to record it. You could record your favourite radio shows and then listen to them on your way to work on the train. Just an idea.
