Copyright infringement and the music

I have said it so many times i think its become a mantra to myself. I cannot sing or create music. At all and that is a big problem that I have to face in the creation of my main project since what is a music video without music?
So the plan was to beg and beg for a band to give me permission to use one of their singles, because getting the permission from the creators of the work is better and way cooler.
So I riffled through songs and scoured the net over and over looking back and forth from music that I adore and music that I just recently found then in my little racket of a phone reminded me of my most played list and number three on the list is the song Escape by Neonfaith so feeling inspired by the song i start reaching out to the band and withing hours they replied, giving me the green light on using their single.

Lo and behold the awesomeness of the band!

So whats next? I hear you say, well next is the actual idea of the Video, creating the concept relies strongly on the mood the influence that is given by the music.
I hope to make the Band proud and also feel like I've worked myself to the bone in this project, so i will update the blog a lot more with updates but i feel very positive in the progress and direction in which its going. But as me and the band spoke i realized that i could create the Short film music video, because they had only released songs and their combined time is 13 minutes and 8 seconds, withould clipping the song. so i quickly inqured if i could use alll of their songs and again being cool with it they gave me the go ahead.
