My husband is developing a software program which he intends to sell for profit. In order to advertise his software, he has made an informational video that he is publishing on his website for general internet consumption. This video will not be part of the software program that is for sale. He is wondering if he can use a piece of popular music (e.g. the "Top Gun" theme song) as background music for this video.
Thank you for your time and any help you can give would be appreciated!
