A chart whore is a phrase used for people who have no knowledge, nor interest in any artists that haven't appeared in the charts.
Example of a chart artist: Shakira

Example of a chart whore: Jack: What artists are you liking at the moment then?
Jenny: Oh, Rhiana, Shakira, Black Eyed peas. That kind of stuff.
