The term “cover” is simply a recording of a previously recorded song, not done by the original performer. The artist making the cover might record it to such a degree of imitation that the listener can't tell the difference between the original and the cover. Quite often the cover version is recorded in the sound and style of the imitator, putting their own mark on the song without changing it entirely. Then sometimes, the cover becomes more popular than the original. An example of that would be...All Along the Watchtower, written and recorded by Bob Dylan then covered by Jimi Hendrix. But that might be in Volume Two...or Three.
