Windows Moviemaker problems. :/

Okay, so I was trying to add music from my iTunes library to the timeline on WMM for a video.
So I went into 'import music or audio', clicked 'iTunes library', 'iTunes Music', the group, album, and then...it came up with nothing.
The songs weren't there.
If I hold the mouse over the album file it says it has the songs, but when I click on the file it comes up empty! :[
Do any of you know what could be causing this and/or how to fix it? Am I just clicking on the wrong stuff?

Yepp, Itunes is a whole 'nother company, so it will not let people just click and drag their (purchased or not,) music to any other program. In english, you can't get your music for your vids from Itunes :/

But what I do is just record the songs. Like if you're on youtube, you can record the song. Search Youtube for some tutorials, thats how I learned. Once you know how, you can record any sound or noise :] woo!

Oh, ok. That stinks a little but I get it. :/
Thanks so much for your help! :]
*runs off to find tutorials*

I have another one because Alley's isn't cool enough. XD

You google 'youtube downloader' and download the newest version. Then you find the music you want and pull up YD and enter in the vid's url in the box. If you do try that then just ask me for further instructions...XD
