"building upon them" means stuff like creating modified versions of the material (ie, the sample). Having to extend the license to music created using these samples is insane and I've never heard of that except in the case of the GNU GPL. But CC doesn't do that.
The license holder of a sample doesn't have the right to tell the author of a piece of music what license to release his music under because the copyright of the music naturally rests with the musician. Licenses don't get extended to entire symphonies like that. Because if that was the case, you could never use more than 1 sample pack in your music...
CC was also created for other things than sound samples I believe, the material it refers to is usually an image.
But I doubt any of us is a copyright lawyer.
