I stumbled upon an interesting old usenet thread discussing the difference between a "cover" and a "remake". You can read it at http://groups.google.com/group/rec.music.rock-pop-r+b.1960s/browse_thread/thread…
The main difference between the two is that a cover is supposed to be made during the the time period of the original, while a remake is done in a later period (ie a song from 1940 done in 1990).
It's an amusing discussion but personally I don't think such a distinction should be made, even if "remakes" are made in a different context or interpretation.
