Just to not disappoint you, we are working on support for
strong-encrypted tracks, so we hope we can support your HiMD as well
in future.

Regarding ATRAC3+. It's true that ffmpeg cannot decode ATRAC3+ files
to date, however, Michael forgot to mention that there is already some
reverse-engineering of ATRAC3+ going on and the guys from ffmpeg are
actually looking to start implementing it.

So, in both cases, we just have to be more patient ;).
