I'm looking for a way to record streams from the iTunes integrated online radio. -> I want to record a radiostation wich is availible on the iTunes-radio...
WireTap's free software that'll record any audio playing on your Mac. I can't think of any way to directly capture the stream from iTunes, but this'll do the job. Just make sure you turn the alert volume on your computer down when doing the recording -- any sounds your Mac makes are included in the recording.
Also, you can use WireTap to record the music from the iTunes Music Store's music videos! It's not great quality, but that's enough for cheap people! ---fcodc---
