I now interrupt this thread to say that the songs that sounded "better" on AM sounded better on the AM radios that existed back in the heyday when those songs were hits! Not on the crappy, tinny AM radios that are out there now!
I now return you to normal programming.
Since I have only ever been using hifi AMs, I forget that most don't have this luxury.
But I take the hi-fi for granted.. Thank you for pointing this out. Generally the problem is too-narrow bandwidtrh on
the medium to expensive radios, making them muddy on AM. Cheapies have wideband (good high frequency) response but tiny speakers.
If you want to hear how
songs can sound better on AM, you need to have the right radio.
Songs heard yesterday on AM which sound better on AM.
