Development of Creative Commons licenses

[Chris Morris <the.chrismo AT gmail.com>]

Does the sampling license allow me to make a derivative work, like the
attribution or share-alike varieties? If there's a distinction, is
there some sort of FAQ documentation helping to define the
differences?

For example, I made a derivative work of Funktifyno's Funkberry Jam by
just adding a keyboard track to the existing piece. Can I do the same
thing with material under either of the sampling licenses used at CC
Mixter, or is just adding a keyboard track to the entirety of a track
too similar to fall under 'sampling'?
