"Low angle shots are used more extensively in music videos, partly because they reproduce relations among the audience, performer and stage. Such shots confer authority upon performers and assert their sexual charisma, often crudely, by highlighting the erogenous areas/zones of performers. On the other hand high angle shots in music videos, as in film, give the viewer a sense of power and mobility."
To summarise a low angle shot gives the audience the impression they are watching a performance and constantly reminds them that what they are watching is a music video, where as a high angle shot gives the opposite effect.
