Just and idea... (Score 2, Insightful)

Instead of paying a buck to figure out the name of the song you just heard on the radio.. you could try calling the station and asking. I have called a local station a few times in the past and they've been more then happy to tell me the name of a song they just played.

You could try their website as well, a lot of stations are putting their playlists up on their sites now; as long as you have a good idea of when the song was played it should not be to hard to figure it out.

And of course as others have mentioned, the almighty Google.
I just can not see anyone paying a buck to figure out a song title.
