If you compare the sales of Kiss me Once in the UK to other established artists, Kylie is holding her own. Her Christmas album clearly sold over 100,000. She managed a top 15 single, a number 2 (Kiss me Once) album that has sold around 90,000 to my knowledge, Madonna, Britney Spears etc have not come close.
Sadly Kylie is past her peak but i agree she has nothing to prove to anyone, she is a highly successful artist.
Not releasing a ANTI Tour Dvd was a blunder as it appears hugely popular with her fans and many of her fans missed out on seeing it live.
I am looking forward to her next studio album to see the direction and sound she moves with. Kiss me Once is and remains a let down and i would regard as a very weak Kylie album. I would like to think she will take her time so she can release a full pop album as promised. I believe i read somewhere she has 3 songs recorded for the new album.
I welcome the work she is putting into the Christmas album and i would hope she does the same with her next proper new studio album.
