I personally disagree, but since people have asked me to make Emms
available via ELPA I'm disregarding my personal opinion on the matter.

Yes, that is the goal.

Once it is on ELPA, would that make the MELPA version redundant? Are
packages duplicated across ELPA and MELPA? If so, why?

Emms is hosted on Savannah, and I'm guessing that GNU/Linux distribution
grab copies of the release version from Savannah/GNU servers as well, so
even if we had those numbers, I wouldn't know how to make sense of them.
