Joye and Fennis studied the effects of line orientations on record album covers; it is likely that their findings can be generalized to other contexts. The researchers report that “Based on the perceptual preference for visual stimuli with cardinal (orthogonal) over oblique (tilted) line/edge orientations (a phenomenon known as the ‘oblique effect’), albums with a predominance of cardinal line/edge orientations in their artwork should perform better than albums with more oblique artwork, as indicated by the albums' market performance and consumers' listening behavior. Study 1, using secondary data, shows that the cardinality of album artwork is a positive predictor of the cover's esthetic appeal and of market performance as evinced by its position in the US charts, expert ratings of the album, and the number of weeks the album remained in the US charts. Studies 2 and 3 use experiments to show that consumers listen longer to music when album artwork is relatively more cardinal than oblique.”
