Urban oldies 1070/WDIA-Memphis is #3 with a 6.5 in the overalls.
Music sounds good on A.M., especially in A.M. stereo; it's the radios that sound terrible. Most made today have a bandwidth of 3.5-4kc/s.
Yes and no. Yes, most radios sold these days have terrible bandwidth.
Yes, AM CAN sound good. IF engineers, not programmers, have control of the processing. IF systems are well maintained. IF the decision is made to go for audio quality rather than for distance/loudness. What????
All-talk stations don't need much in the way of audio quality. CRL still makes a device that squashed bandwidth down to noting but allows the signal to really get out there. It's loud and it has reach. Best example of good use of the device was the old WHDH-850 when they were exclusively talk. Put music through it and it sounds terrible.
Best example of excellence in audio was the old WJAR (920) Western Electric Doherty Linear 5-kW all "fire-bottle" transmitter built in about 1930 and kept as a backup well into the 1960s or beyond. When Roger Perry was doing a lot of their engineering he'd find any possible excuse to fire it up and, if you had a decent radio, you could tell immediately. Those transmitters, great as they were (WSAR's old GE, long gone) was almost as good), chewed up way too much power and couldn't be run economically. More, tubes were hard to find and pricey. Even more, you had to be an engineer, not just a license-school grad to make 'em sing.
Despite what a good engineer can get out of even today's transmitters there is so much electrical noise in the urban environment that it's a losing battle. The quality may be there as the signal leaves the antenna but, by the time all the trash messing up the spectrum gets through it with it the results are far from optimal. Plus, most of today's listeners have had their hearing ruined by blasting ear buds that it's questionable how much difference good audio quality makes.
