|Keep It Simple track listing|
Morrison described the meaning of the word "entrainment" and the music on the album thus:
- Entrainment is when you connect with the music...Entrainment is really what I'm getting at in the music...It's kind of when you're in the present moment - you're here - with no past or future.
"That's Entrainment" was played for the first time, at the beginning of the second hour, on Chris Evans BBC 2 Drivetime show on Wednesday, January 30, 2008, with Evans commenting "The new Van Morrison album came with a shoot to kill warning if played before a certain date, but that's now been lifted so we can play it."
