Can I download radion file and listen to it later

[ffish]

I want to listen to the radio on the computer, but I want to download the multimedia files(story, news, etc.) at first, then I can listen to them later, some radio web sites only provide stream files which can't be saved on the
hard drive, which web sites offer files download so users can listen later?
or are there any Freewares that download the stream file into the hard drive?

Thanks for help!
