Music Licensing woes

I have an introduction video ready to use on my youtube channel, but the template uses a sample of music from a commercial artist. Since I do not condone theft of music in anyway. I have sent a request to the artist and his PR contacts to use the audio sample with permission. So far I have been sent contacts for 5 different people, and have sent a total of 7 emails on this one request.

Once you get into the commercial realm of licensing be prepared to spend more time sending requests then you will actually get anywhere.

Not a single response back from the companies “Get In PR”, & “BMG Music”. I understand why the media companies complain about people stealing content, they do not like to do any work to keep things legal.

I sent another email today and attached each person in the send field.

Got a response back from one of the people, and was told he included the other people as a CC, included a docx form for me to fill out and return to them. I filled out the information to the best I could, and mailed it back to him at 7:41pm

Still no answer back, about to give up on it. I am going to look for alternative music to use. If this is how long things take for the music business in general to get anywhere I truly understand why so many artists are leaving the big companies and starting a company themselves

I have given up on trying to obtain permission on using the music track. It is only 7 seconds of audio which I am positive would fall under fail use but because of how I was treated by never getting any responses back I will never work with BMG on any promotions or advertisements on the channels. In my last email to them (sent to everyone) I told them I will be making the contents of the emails public and also making a youtube video about this and the lack of responses I was given.
