You have a point there. In fact, many of our sounds (around 50%) have that matadata already.
Many have requested this and we should probably make it a requirement.
Although it won't work for music loops, since producers hardly know what Soundminer is..!
As soundminer is the standard application for sound archiving (at list in film post pro) it would be great if sometime in the future the soundsnap sounds could have metadata embedded in the soundminer format.
