Iggy Azalea: Work
http://www.dailymotion.com/video/x24j3r8_iggy-azalea-work-explicit_music
There's basically three speeds in this one:
1. Very slow strokes the first 30 seconds and when she enters the bar (1:52 til 2:05)
2. Normal speed (naturally with the beat, the spead of every single word in "no money, no family" for example) - majority of the song
3. Double speed - During the refrains (when there is nearly no singing) plus whenever she says "work work work" with a nice long finish stroke for "on my shiiit" :) and then briefly back to normal, until you work work work again.
4. Mandatory edge at the end of the second refrain - which coincides with the end of the lapdance :p
