Have you ever been listening to the radio and wondered what song was playing? You wait until the song is over, hoping the DJ will grace you with the title before starting the next track—sometimes you’re lucky, other times you listen intently for several songs afterwards and still never get the answer.

Given that this is such a common occurrence, it was intrigued when I came across a piece of software whose sole purpose is to tell you what song is currently playing on the radio. But when I read that the software claims to perform this feat by actually listening to your radio and recognizing the track, my first reaction was, “Yeah, right.”

And yet Wildbits’ free Tunatic v1.0b does just that: After launching Tunatic, you hold your Mac’s microphone near your radio’s speaker, click the “search” button, and wait for Tunatic to identify the song.
