It's nearly over. Neeeearly over, now. With Rylan Clark out of the competition, James Arthur, Jahmene Douglas, Union J and Christopher Maloney battle it out in the semi-final, choosing tracks with the themes Songs for You and Songs to Get You into the Final. Gary Barlow, Nicole Scherzinger, Tulisa and Louis Walsh will be looking for nothing less than note-perfect performances from the contestants as they search for a worthy successor to last year's winners Little Mix. Who've gone on to dominate the charts *tumbleweeds*
