When listening to the radio it is common to find an interesting song of which little or nothing is known, although it is true that there are programs to identify that song, usually the most comfortable thing is to record the song on the computer and then identify it more calmly.
One of the best programs to record any sound that passes through the computer is SoundTap, which allows you to record that special song from the radio to any other sound that passes through the PC, including, for example, conversations in Skype that need to be archived for any reason.
SoundTap is a very intuitive program, so you shouldn't have any major difficulties in starting to record the sounds that pass through your computer at any time.
