I once had an ‘Intempo Rebel’ radio[1], about a decade ago, which had the selling point that it would record songs, from radio, as MP3, without any ads or DJs. It actually worked, from what I remember. It was magic to me at the time, and …still is.

Edit: it appears that its original name was PopCatcher [2], by a company with the same name
