I know it's going against the trend here, but I like the new music. It is different to the (News) style music that preceded it, but it fits the more intimate idea of being close to politics - matches the music used on the small in-between programmes - and harkens back a bit to the past of the channel.
As for the look, I am not so keen. The idea is sound, party colours being represented among the gears and cogs. Just adding colour to the previous spinning device, wouldn't work, but the cogs turn quite slowly, and there is little dynamic movement with them.
The logo... It could be aligned better, but is not bad in of itself. It should appear in a more dynamic way, and should be less subtle.
And of course the on-screen graphics should be updated - not just the logo, but the whole style of it. I guess it is just a sign that it was done in a non co-ordinated way.
