J.dillas "bye" track from his "Donuts" album.
YouTube - Broadcast Yourself.
The swirly sounding keyboards? Kind of a gargling sound that start at 3 seconds. Any ideas?

The sample comes from a track by The Isley Brothers called "don't say goodnight (it's time for love (parts 1 & 2)" and the sample must have been originally played by Chris Jasper,
