I meet Corinne Bailey Rae upstairs at Ronnie Scott’s in Soho – she wanders into the room and a couple of record company types intercept her. I hear phrases like “consumer segmentation”, “demographics”, “functionality of streaming” floating across the room – it sounds like someone has a new type of iPhone app they want her to sign up to. She looks polite, if a bit bemused. But in a depressed record business, Corinne Bailey Rae is a really big deal.
