In the United States, music on AM is dead because research has shown that nobody would tune to AM for music.
Well, it's a bit deeper than that. In the US, AM attracts nearly nobody under 55 or 60. The only exception seems to be for sports, and as that format and genre moves rather rapidly to FM, the only AM listeners will be those looking for religious or niche ethnic offerings.
In the Philippines, however, there are still AM stations that play music. Manila, for instance, has a powerhouse on 774 AM (DWWW) that plays Adult Standards. That powerhouse puts in a good signal to Olongapo City, which has only 3 FM stations and 1 AM station. IMHO music on AM is beneficial because it enables people in rural areas, e.g., rural South Dakota, to listen to music.
Have you looked at the coverage of the Class C FMs up on all those 2000' towers? There is a lot of music on FM available in the gas fields and in those neat air conditioned tractors, too.
The business model of media and radio in the Philippines may be different than in the US. Advertisers may buy regional powerhouse stations to cover wide areas. And they may buy formats like Standards that are dead in the US because they reach ages that advertisers here don't want to reach.
In the US, if it targets 55+, it won't work well on AM or FM or CB. If it has coverage outside the local market, it won't bill any more because of that, because advertisers buy city by city (except for the thin slice of network, wired and unwired) and just don't look at outside coverage.
Add to that the fact that most AMs, even in the Dakotas or northern Maine, don't have any decent coverage outside of their little towns or cities. For every KRVN, WNAX and WMT or KWMT, there are 500 stations that barely cover their home market.
The big US radio conglomerates ought to consider folks in rural areas and consider returning music to AM.
There is no business model and no available revenue for this.
In the meantime, in the US, you must live in the city to have access to the FM music stations.
Pull up the FCC coverage of the FMs around the great plains states. The 60 dbu of the C's in Bismark is about the same as the 5 mv/m of KFYR, so there is certainly a lot of music being offered. Then, look at the audience on the #1 12+ station, KBMR... a music AM. It is barely Top 10 in 25-54, and is among the market's lowest billers while stations with a quarter of the 12+ but good 25-54 beat them by double, tripple in billing.
