This sounds very similar to what went on with WLYF in Miami. I had noticed something about WFEZ and WLYF at least. They're the only Soft AC and Mainstream AC in the Miami-Ft. Lauderdale market for the past six years. WFEZ had gradually filled in the gap between Soft AC and Mainstream AC over the past decade as WLYF had quietly became a Mainstream AC completely over the last half of the previous decade. WLYF used to be a Soft AC / Mainstream AC hybrid back when I started streaming it in November 2011.
I think WLYF had evolved in a similar fashion to WEZV, except WLYF done it quietly. WLYF had slowly dropped a lot of the Soft AC tracks between 2014 and 2018 that it used to lean heavily on up till 2014. Since 2017, they had been adding more recurrents and currents than they ever did. Around late 2018, they dropped their "Refreshing" slogan in favor of their current "Real Music Variety" slogan. They still kept the same branding and logo.
I forget where I posted about it, but I looked at WLYF's last songs played and compared to WFEZ's list and there were a lot more similarities than I would have expected. WLYF had not gone as far as WEZV.
Actually, now I'm looking at WLYF's last songs played and it is quite similar to WEZV. And lots of 80s. Their HD2 channel is really good, though.
