To me it's a bit of a gray area, I remember seeing something similar with sports statistics apps with separate team themed applications. I've already seen this on the Windows Phone 7 marketplace where someone spammed separate applications for single currency conversion (USD => NZD, NZD => AUD etc) and can see why you want to remove them. I think to get around this sort of restriction mass application submissions will really need to differentiate between applications a lot more than a single feature. Possibly content from that radio station, contents, news etc, hard to tell what will meet with approval.
