HunchBluntley: But that's one of the terms used, though it's pretty generic with regards to medium -- a film or a video game can also be a remake, for example. The music-specific term is
cover version or
cover. This specifically means a version of a song performed by a different artist from the one who originally recorded, wrote, or popularized that song (which seems to be the case with the Disturbed track).
A
remix, on the other hand, usually means a version of an artist's song which still contains elements from that artist's recording of the song (typically including at least some of the original vocals), but which might also contain new elements introduced by whoever did the remix. In some cases, what is called a "remix" is almost completely composed of new material, without even the same musical arrangement left over from the original recording. (Then again, at the other end of the spectrum, there's also the sort of remix that's nothing more than -- for example -- the original producer or engineer going back and tweaking the mix of the instruments, making the bass more prominent-sounding or whatnot. A remix in the technical sense, but not what most people think of as such.)
To further confuse the issue, there are also often a number of mixes (also called edits or versions) of a song. They're not
re-mixes, because they are released at the same time as the original. A CD single (back when people still bought those) often contained maybe 5 versions of the same song, such as "Original Album Version", "Radio Edit", "Club Mix", "Instrumental Version", etc.
