This was certainly heaps better than Ariana Grande, though admittedly that is not saying much.
Both superficial and lightweight pop artists, Minogue benefits from her 30 year long experience and capacity to pick talented people to work, thus ensuring a higher overall quality. This is still not my type of Christmas album, but it's passable.
(That posthumous duet with Frank Sinatra, however... When you are an average talent, it's generally a good idea to stay away from immortal legends.)
Instead, listen to Michael Bublé, Mary J Blige, Babyface, Barry Manilow or Barbra Streisand!
