The first single from Kylie's Greatest Hits, What Kind of Fool (Heard All That Before) was co-written by Kylie and Mike Stock. (Pete Waterman was also credited, although he never really wrote anything ...) Sonically, it sounded like a leftover from her Rhythm of Love days and probably confused fans who expected something that fit more with the R&B/Dance leanings of Let's Get to It. It peaked in the top twenty in both the UK and Australia. It remains one of Kylie's least performed singles, as she doesn't like it - she "cringes" thinking about it. (She did do some, acapella, at her recent Anti-Tour.)
One of the last track to make Let's Get to It, but a good inclusion - as it was the biggest hit from that album. Peaking at number two in the UK, and somehow going number one in South Africa, GMJALMT provided the hook that most of her newer material lacked at the time.
Picture this. New York City. October 2009. A youngish homosexual gets his dream graduation present. Screw a car, he's seeing Kylie Minogue.
(That's me, by the way).
During her first (well, technically third) performance ever in NYC, Kylie debuted a new song she had been working on. It was loved instantly by these ears.
The charts didn't feel the same way a year later.
Neither did you fools.
The only single off of Aphrodite that works bar the first one. Sure, it doesn't have the majesty or poignancy of All the Lovers, but nothing on that album does. It's so much more Kylie, with a genuine wit, a tongue parked firmly in cheek, a nod to camp, and experience in the vocal. It bypasses the autopilot of Put Your Hands Up, and entirely skips the crassness of Get Outta My Way. Truly special, although I will admit the album/single version doesn't hold a candle to the live demo.
Did you know that Butterfly was slated to be the fourth single from Light Years? It was deemed to club-reverent (read: gay, which is saying something considering what else is on that album ...) and was relegated to the album.
But it was released to clubs. It was one of the first songs from the album to be remixed. It didn't do anything on the UK club scene, but went top twenty on the US Dance Charts - Kylie's first US chart appearance in many years.
Co-written by Kylie and frequent (and best) collaborator Steve Anderson, Butterfly is a gem; a gem I'm surprised Michael didn't get.
But I knew it would die soon, it's a bit meh. 
Kinda surprising, but there are many other better tracks than this. I love the gay vibe of this.
