Yes. To use a track from the library for your project you must obtain a license.
No. Feel free to download the track you are interested in and try it with your project.
This fee varies based upon the size and scope of your project. I keep my rates competitive with other music libraries but am always willing to work with the price for smaller-budgeted projects.
A license grants you use of a Little Gettysburg Music track for all media, in perpetuity for your project only (not other subsequent or related projects)
The standard license is for non-exclusive rights. Meaning I can license the same track to someone else. In the event you want exclusive rights, I am always willing to discuss the option.
I am willing to make simple changes (trim timing, rearrange sections, etc.) free of charge. More detailed changes may require an additional fee.
