Thanks for sharing. I don't have much time to research the names nor I am also not an expert on co.uk.
I have seen much worse. I like acousticmelody, but the others are probably not worth much.
My suggestion would be to really, really wait before registering domains. Make out a list of the ones you want and wait a week or maybe two.
If you are still as excited and have done your research, then register it.
Without knowing your plan (resell, develop, etc.), it's hard to tell you much more.
Also consider checking Namebio for similar names that have sold.
Best of luck!
