Blake Williams died in 2017.
Are you sure it isn't Don Davis' prerecorded soundbites at night?
I checked it out last night and it certainly sounds like prerecorded soundbites just saying things like "more music on The Oasis coming next" etc. with no mention of what songs are being played. I'm not sure whose voice it was but it wasn't Don Davis.
I have another list of what played for about 80 minutes straight starting at 4pm.
Fast Car - Tracy Chapman
Angel of Mine - Monica

Never Too Much - Luther Vandross

The new slogan does appear to be "The Heart and Soul of New Mexico". All of the music does seem to have a Soul/R&B/Pop sound and about all of the songs are from the 1970s-90s so it is entirely a gold-based format. The presentation is not too different from before.
