Radio Rip for Android will capture online radio streams, but many streaming providers block access to such apps because they would want him to use their app in particular. Leo's show is streamed through Clear Channel's iHeartRadio app. Radio Rip captures mp3 streams, which is not how most commercial radio stations stream. Unfortunately it just isn't compatible with apps like Radio Rip. He could, however, capture TWiT's audio stream at twit.am/listen of the radio show instead.
