Dooky, to elaborate a little more I feel there are different moods when it comes to getting nasty and I'm sure you feel the same way. The style I like is a little more aggressive and fast paced compared to Barry White, Marvin Gaye, Boyz 2 Men or whatever you have listed.
For example:

and that album is nearly 15 years old but it gives you a good idea.
