Final answer:
A cover is indeed when an artist re-records a song that was previously recorded by another artist, often with their own style and interpretation.
Step-by-step explanation:
The statement is true: A 'cover' refers to a new performance or recording of a previously recorded, commercially released song by someone other than the original artist or composer.
When an artist creates a cover, they interpret or give a different perspective to the song, which may result in variations in style, arrangement, or instrumentation. Covers can often lead to the song gaining a new audience or achieving recognition in a different musical genre.
