Help!!!

I need a help to find the song,
but I have few clue.......

I am not sure if this song is pop or R&B.
(Sounds like R&B.....)

Two males sing this song.

I hear the following words in the song, and I don't know the complete lyrics:

(It's) time to get it on
Let's get it on ←this is how the song starts.

~~~feel good
~~~ecstasy
~~~direction←these three words I can catch

down down down down ......(Repeat)

I am so sorry that I cannot explain more......

Since I'm a foreigner, I cannnot think of more words other than I listed on top.
What I remember is that this song is covered in an Omnibus CD.

If someone can find what it is, I really really REALLY HAPPY!!!!!

The down down down one is

Paul johnson get get down
