DFSG requires permission to make derived works, which is usually
interpreted as *any* derived work for *any* purpose. The gap here is
that there's no permission to use the work in a free software work
that is unrelated to "APE format playback, encoding, or tagging
support". Hence, fails DFSG §3, and possibly §6.

This is so ambiguous I can't discern what it's allowing or
forbidding. It's not clear whether this permits redistribution, and
there's no further permission elsewhere, so I have to asume there's no
permission to redistribute. Fails DFSG §3.
There is also no permission to redistribute a work under the terms of
*this* license. Fails DFSG §3.

Fails the Desert Island test, and possibly the Dissident test, by
requiring any redistributor to contact a specific party unrelated to
the recipient of the redistributed work.

I can't see how this requirement could ever be met by anyone. "Any
... ideas ... used must be plainly acknowledged"!?
Probably prevents anyone from meeting the license => not useable at

Disclaimer of warranty => fine, though perhaps overreaching what can
actually be disclaimed.

Goes beyond what copyright actually allows the holder to require; only
acts of copying and redistribution are within the purview of
copyright, so the holder can't demand that you remove the copy already
Anything that pretends to be an "agreement", that must be agreed to
before *using* the source code, renders the work non-free.

It's not clear where the license ends; "All rights reserved" is in
conflict with all the other grants of permission in the license, so
should be removed.
Conclusion: This appears to be yet another invent-a-license with many
ambiguities and lawyerbombs. The author would be well advised to
simply license their works under an existing, well-understood and
peer-reviewed free software license instead.
