The music throughout the whole video is quite upbeat and jumpy also becoming catchy as we can easily pick up on the words. Although it is quite happy video it has an emotional side as well.
This is a good long shot as it shows the singer but by being surrounded by a group of people takes the full focus off her and more towards her surroundings.
This shot gives a direct view of the main singer showing clearly what she looks like and the expression on her face. This also collects the audiences attention and make them link/connect with the character as she is giving direct eye contact. Having this closeup shot gets the audience more involved as they feel directly linked to whatever is going on sustaining their attention and interest.
Random shots such as this puts the audience off track and as said somewhat confuses them as they are unsure of whats going on, it keeps and remains their attention and interest but this shot is simply to show the moving pavement and possibly the idea that others are experiencing it as well. Its edited so the pavement and everything else moves at different speeds, the video starts slow and then speeds up could yet again represent the idea of time.
This shot also links to the idea of being 'alone' as the singer is shown in a surrounding where there are no other people. But although she is alone she looks somewhat inferior to everything around her and she remains quite tall and strong compared to that of someone who was sitting hunched into a ball etc. The idea of her being like this could possibly reflect her mental or emotional state e.g. although she is alone or missing/without someone she is being strong.
Abstract and interesting shots give the video an exciting twist and yet again sustains the audience's attention. It also confuses us in some way, telling a story but in a unusual and not obvious way so we remain focused as we want to find out what happens.
The idea of the pavement constantly moving could suggest or indicate a busy, non-stopping life or directly link back to time as in time doesn't stop or slow down. This could possibly mean that time has moved on or that time could be stuck in the past but remains moving. The surroundings are quite empty and lonely and for me personally give an idea of being 'lost' or venturing into the unknown.
At the end of the video it shows her being reunited with a boy in which we see frequently throughout the video telling us he is involved in some way. Although the fact they are situated to the right of the screen shows they are somewhat hidden possibly secret as they don't gain the audiences full attention (middle) They are also under shelter by a building where the other side of the screen is quite open and free this could possibly show an idea of being trapped or stuck or could reflect back to the idea of time e.g. time moving or slowing down.
