Copyright clearance

During our summer break were asked to think of a few songs we were interested to do a music video on and then contact their record labels to ask permission if we can use their artists song.
I sent three requests to labels asking for permission.

Architects - An Open Letter to Myself

You Me At Six - Stay With Me 

Kasabian - Underdog

All three of these songs i have asked permission for is all different genre's, although they are under the main genre rock there is many sub-headings of rock.

Architects are a scremo band, You Me At Six is a alternative rock band and Kasabian is a indie rock band.

These are all very different genre's when compared to each other, do not assume they are all just rock.
