I don't think they showed her range, though... I mean, they did well because they were in all kinds of TV shows and movies (hearing W.G on "Power" on Showtime was surprising!), but I'm not sure that the marketing strategy was the best, which is what I was getting at. It's probably not under her control, so by "her" I meant her team.
If she makes a less artsy video for one of the softer tracks, she'd expose parts of herself that she hasn't yet through singles and attract new people to build on to the audience she already has.
