Yeah Madonna with JustifyML, Erotic, Jump and even Muzik is very useful as well as GMichael (oldies and recent stuff, he knows how 2do it)

Generally, there are some other pretty nasty tunes, for instance:
Britney's Boys or Kylie's Boy etc - very animal_magnetizm-like too,
From Enigma - i'd suggest the principles of love
from the gold hits:
100% pure love (now available in remixes)
Show me love and Night Crawlers things (same)
But, i'd consider that ocean_sounds as well - pretty arousing
