Have you ever had a song in your head that repeated itself over and over again?

Well, that's what happened to my husband a few years ago. The music in his head was especially overwhelming because he didn't know the name of the song.

To him, it was a melody that he loved, so he had an urgent need to find out the name of the song. We went into music store after music store where he hummed the tune. But no one could come up with the name of the song.

Then one day, while shopping, we heard his haunting melody over the loudspeaker in a store. My husband, believe it or not, went around the store asking if anyone knew the name of the song. Someone in the store was able to recognize it. The song was "La Vie en Rose," and it has since become one of our favorites.

I couldn't help but think of this incident when I recently found a great Web site called Midomi (www.midomi.com).

If you have a microphone hooked up to your computer, you simply go to the Web site, click on the icon that says "Click and Sing or Hum" and give your best shot at singing or humming the melody. When you are finished, just click "Done."

Even if you can't hold much of a tune, Midomi usually comes up with the correct answer. It is amazing!

When you are presented with the Midomi results, you will see the name of the song and any famous artist who sang it. You can also find links to videos of performances of that song. In addition, you will see recordings by Midomi Web visitors who have recorded that song.

Anyone can record songs on Midomi. You can actually go to the Midomi recording studio and record your own voice, which will then be added to the Midomi database to help recognize songs.

Of course, if you click on a song in the search results that was recorded by a recognizable artist, you will get a preview of the song and a link to Amazon or iTunes, where you can buy the song. But you will also get links to others who have recorded the song at the Midomi Web site. It's pretty interesting.

This is a real music exploration Web site. You can find some very good voices who have recorded music -- some a cappella, some with a singular own guitar or piano, and others with complete accompaniment. You can follow any Midomi artist or find new ones.

For instance, I sang "Rainy Days and Mondays," a song that was made famous by the Carpenters.

My Midomi search results featured the Carpenters, along with videos and links to buy, but Midomi also came up with a Midomi artist named Fallingsta. She is a young girl from Spain whose voice is as good as, if not better than, Karen Carpenter's. That led me I found that she had made 69 other recordings.

Well, you get the idea. You can spend a lot of time investigating music on Midomi, but you can also find a lot of enjoyment.

In the past, I've used a service called Shazam, which is a free application for the iPhone and can also be used on the Blackberry and several other cell phones. With Shazam, you start the program and hold your iPhone up to the music and it will identify the song that is playing.

Midomi is also available as an application for the iPhone. It is better than Shazam, because you can have it identify the song that is playing in the background as well as a song that you hum or sing.

Unfortunately, Midomi for the iPhone costs $4.99. So the free Shazam will stay on my iPhone, but Midomi will be my "go to" when I have a computer in front of me and a song in my mind.

Midomi has taken the idea of song identification to a new level. No more searching music stores or humming songs to friends and family. If you want to identify any song, just head over to Midomi. It's a great Web site, and it's free.

I just wish it had been available a few years ago when we spent months identifying "La Vie en Rose."
