MELBOURNE: Victoria Azarenka walks a fine line on court, her demons bubbling just below the surface, but the tempestuous world number three would rather feed off the full spectrum of emotion than live life in black and white.

The Belarussian stepped on court with Keri Hilson's "Lose Control" pumping through her iPod ahead of her Australian Open fourth round match against Iveta Benesova Sunday, and while the emotions were kept in check for the most part it took a burst of passion to get her over the line.
