I've been trying to figure out why I dislike this kind of thread so much, and I think I know:
"Dream dials" like this, when generated in bulk by people with no real knowledge of the markets they're "surveying," contribute nothing to an intelligent conversation of any given market's radio scene. Instead, they promote exactly the kind of generic homogenization of the airwaves that so many of us on these boards (and in real-life radio) detest: if market A has a rhythmic top-40 station called "The Beat," then markets B, C, D and E should have them, too, right?
Well, no.
Each market - even ones as close as, say, DC and Baltimore - is a world unto itself. Some markets have little audience turnover and thus strong attachment to heritage brands and dial positions. (DC is a good example of this: country and 98.7 have gone together ever since WMOD became WMZQ. You don't mess with that.) Others have lots of turnover and very little in the way of "heritage" stations - as big a player as the old KFM102 was in Las Vegas two decades ago, it would make no sense to resurrect it now, because nobody's around now who was listening to it then.
There are all kinds of signal nuances that help to explain why some formats work on some frequencies in some markets and some don't.
And of course demographics vary wildly from one market to another, as the discussion under XCountry's LA "dream dial" bears out. It makes perfect sense to have half a dozen or more Spanish-language FMs in Los Angeles. You couldn't do that in DC, or Pittsburgh, or Cleveland.
My point, I think, is this: if someone wants to take the time and effort to really learn about all those bits of history and nuance to create a "dream dial" that makes some kind of sense, I'm all up for that conversation. But to just take a list of frequencies (in this case, some of them not even DC stations - there are pieces of Baltimore in this list with no real rhyme or reason) and assign random formats (or in some cases just meaningless descriptors like "public radio") and generic slogans to them? I'm not sure I see the logic behind that.
