There are two versions of the game, single player and challenge. I just tried single player because I was curious how well I knew my own music library. Of course, I didn't take into account that since I listen to a lot of movie soundtracks, there are a lot of 3-4 second samples of the music that sounds, well, remarkably alike, especially when they're from the same composer.

That's what the game does, btw: It plays a very short snippet from one of the tracks in your music library, selected at random, then shows you three possible matches from your library, one that's correct and two that are not. Oh, and it's all timed, so you have to be fast!

Anyway, the problem of music soundtracks all sounding alike? That's my problem, right? The question was: how well do I know my own music library?

To get started, I downloaded the app onto my iPhone and started it up. It shows up on the iOS device as "Guess Songs" and upon launch shows:

Great. I immediately tap on "Play Game" and find out that the program has to index my music library before it can go further:

No worries, it took maybe 30 seconds total before it was ready to play, at which point clicking "Play Game" had a much more satisfying result:

Since it was my first time through, I tapped on "Normal" for difficulty level. I can try harder settings (presumably shorter music snippets) later.

And... the first snippet quickly played on the phone and I was left with three unlabeled choices:

At first I found this a bit puzzling and tapped on the "?" boxes, but then I realized that I needed to tap on "Let Me Guess" to have the different album covers -- alright, "cd covers" -- revealed. It isn't instantly shown because time is a factor. Listen to the audio sample a few times by tapping "play song again" and when you're ready, tap on "let me guess" and the three possibilities are revealed:

Hmm... was I listening to a track from Harry Potter, The Goonies or The Next Three Days?? I was pretty sure it was from The Goonies (music composed by Dave Grusin), so I tapped on the middle album and, well, oops:

A few songs further along the quiz, I got it right:

After each guess, you can listen to the music for a few seconds or longer. When you're ready, just tap on "next round". Finally, after you survive -- or ace! -- ten questions, you'll get a final score:

Seven out of ten. Jeez. I need to pay more attention to my music, clearly!

I have to say that I enjoy playing with Guess Your Songs, it's a fun way to get a handle on my widely varied music library and great for quizzing my kids (though, yes, I know, it's not fair).

The ads that pay for the app aren't too annoying, as you can see, though I will say I wish that the final quiz results were a bit bigger: It took me a while to realize that the last screen wasn't a bunch of adverts but was actually my score and an indication of how I did, round by round.

If you're a music nut, whatever your genre, I recommend this fun and entertaining game, whether you play it on Facebook, the Guess Your Songs Web site or on an iPhone or other iOS device, as I did. Nice job, chaps!
