MB,
Sorry, but you don’t seem to understand how the Station Sound category works in the ntl commercial radio awards.
You can enter either a collection of imaging from your station, or if you prefer a one-off promo, trail, sweeper etc. That is what Leicester Sound did.
Andrew Fewster made his winning entry in Leicester, as part of a campaign of multi-cultural awareness in the TSA. It wasn’t something that was made in Bristol and farmed out, as you seem to point towards.
Equally, Viking FM’s entry item was made by the very talented Matt Robinson in Hull, and the Galaxy stuff was made here in sunny Leeds.
Having done a couple of shows on a GWR-owned station recently, I thought their imaging fitted the music content nicely. No need for sung jingles if they’re not going to work. If you’re IDing yourself in long music sweeps, why the need for sung elements? Roll imaging over intros and the music never stops.
Also, from a jock point of view, the current imaging is easy to use with the music and the playout systems. Having great imaging is one thing, but making it easy to use is just as important.
In my opinion 
Chris
