«cover» - best artists

In popular music, a cover version, or simply cover, is a new rendition (performance or recording) of a previously recorded song. In its current use, it can sometimes have a pejorative meaning — implying that the original recording should be regarded as the definitive version, usually in the sense of an “authentic” rendition, and all others are merely lesser competitors, alternatives or tributes (no matter how popular). However, Billboard — and other magazines recording the popularity of the musical artists and hit tunes — originally measured the sales success of the published tune, not just recordings of it, or later the airplay that it also managed to achieve. In that context, the greater the number of cover versions, the more successful the song.
