I seem to recall the user CHRles who would post these amazing long-form playlists of international dance stations. It was always too much to track down by oneself, but nonetheless very much appreciated. It was a cool time, when it seemed anything was possible in the wake of mainstream dance radio stations of one form or another that were on the air in many major US cities.
We were all hoping for the same radio revolution that happened in alternative rock in the early to mid 1990s to take place on the radio in commercial dance music nationwide. We couldn't figure out why the music wouldn't become huge in the US as it was so accessible and amazing (to us).
100% speculation, but it could have been a confluence including but not limited to the advance of social media, the proliferation of streams to meet anyone's heart's content and the ability to create endless customized playlists from apps such as Spotify & the like that lessened participation in those advocating for dance music on the FM airwaves.
IMO radio is still the most accessible medium. For instance, when i was traveling around last year, it would have taken some effort every time I got in the car to plug the phone in, dial in to some stream (usually jockless) etc. Whereas, I could do nothing and the HD2 of Pride Radio or whatever was booming through the car.
I still love radio and quite frankly, ease of use is a primary reason why. After all, if "old fashioned" radio is providing an equal or even superior alternative to streaming (as is the case I would argue with Pride Radio [that has an airstaff] or even Channel Q [that no longer has an airstaff]), I'm there.
Again this is the case in larger cities. Get into anything lower than a top 50 market or whatever, and generally streaming is an absolute must, unless you like listening to only the tried and true and the overplayed.
This is coming from a music/radio geek and am fully aware that most people use radio (if they use it at all at this point) or any streaming service as an appliance only.
It goes without saying that hearing the latest background noise is enough for most people.
Nonetheless, I still think it would have been fun if pure dance hits had enjoyed more of a run than it did with the remixes and uptempo pop that dominated the charts back then for a while.
