T2 : : Choosing the track/Gaining Permission

We wanted a reasonably unknown source of music for our music video, and came across this, after a big of searching discovered that they weren't that big or known. 

We found the bands website, went to the page to contact them to gain permission about using their song  to create a music video. 

Here is a copy of the audio file of the song we have chosen. "Not my day" by Lost in Society.
