I'm not defending i-Heart Radio here, but that sort of thing happens at all stations regardless of size. Just this morning I was listening to 96.1 Kool Radio out of Connecticut and all the voice-tracks were missing during morning drive. There was dead air at the points where the voice-tracks were supposed to be. Then they starting playing "Billie Jean" by Michael Jackson, abruptly cut it off went to a commercial came back and started playing "Lean on Me" by Club Nouveau. I forgot about checking their sister station 100.1 Kool Radio Springfield via 1270-AM. But what I do know when I got into my car at 9:35 or so to go to Stop and Shop and Walmart Kool Radio was playing "Lean on Me" by Club Nouveau again!
