I don't understand what you are trying to accomplish. However, reading between the lines it seems that by "popular" you actually mean "bands that I like". It stands to reason the "radio friendly stuff" to which you refer are in actuality the truly popular bands relative to the general population.
With the advent of social networking sites like myspace music, etc., and inexpensive recording software anyone can be a "signed band", all you have to do is make up a label name and build a free templated web page. There are numerous examples of that just on this forum alone.
I think this topic; "Bands" already does a good job of covering the limited appeal niche bands, and as you infer the "radio friendly" artists have mega budget PR departments to make sure everyone knows about upcoming releases. Obviously the fact that the “Bands” forum is actually supposed to be limited to bands that use/used Sunn gear is also a limiting factor as far as radio friendly band with upcoming releases, because although some of those bands still get substantial airplay, the vast majority of those artists are either passed away or long retired.
I truthfully have no idea what your idea actually is, but using the word "Popular" in the subject line would indicate an invitation for people to post Justin Bieber's or Taylor Swift's upcoming releases rather than posting upcoming releases from the comparatively miniscule demographic that I suspect you are referring to as "popular".
As I said, IMO the “Bands” forum already has an abundance of limited appeal niche market “artists” represented; and if my guess at what you are trying to accomplish is correct, I think it’s an overly redundant thread idea. But, that doesn’t mean it shouldn’t exist. I would suggest changing the title from "popular" bands with upcoming releases... to “(fill in the appropriate genre)” bands with upcoming releases…
And, what does “ITT” mean?
