It must accompany the derivative work as the license for the parts
that come from the original work.
The license states:

| distributed with all copies and transcodings of the recording or
| substantial portions thereof

I don't think that a transcoding is a derivative work (assuming that I
correctly understand what you mean by "transcoding"): it's a mechanical
(i.e. non creative) transformation.
Hence, the license text must accompany *copies* and *substantial
portions* of the original work.
Not a derivative work as itself: only the substantial portions of the
original work that may be included in the derivative work.

Every creative contribution that is added (in order to obtain the
derivative work) may be under a different license.
If a proprietary license is chosen, the derivative work is effectively
proprietary (until you manage to reextract the parts under the
permissive license, if at all possible).

Hope this clears things up.
