I travel to a lot of different markets and get to sample, but I don't get to listen enough to catch many errors - but I do spend a lot of time in an Audacy market, #59 Greenville-Spartanburg. I can testify that liners often run over/on top of songs, there are accidental overlaps between songs going straight in to commercials, sometimes 2-3 liners play in a row, etc on all of their stations here. The RDS also doesn't work on most of the stations half of the time or list the incorrect song despite no signal issues. It's consistently been an issue even when the company was Entercom. I'm not sure why this isn't something that can't be addressed across the board, or at least on a market level.
I hear tons of iHeart, and then Beasley and even Summit - never hear these issues. The sloppiest sound and most errors come from Audacy. If Beasley and especially Summit can produce a tighter sounding and more organized sound than Audacy, there's a problem.
