This is a new song from Steve Cobby, producer of not one but two of last year's best albums (Everliving and Revolutions since you're asking). Captivated is a sumptuous tune with a lovely vocal by Emma Fee. Steve has calls it bossa-tech-soul which doesn't sound very romantic but is accurate enough. To do it justice you need to switch off from the world for four minutes thirty-six seconds and do nothing but listen.
