In addition, various organizations have licenses for varying uses of a particular musical work.
If you want to use a piece of music in a way other than listening to it privately, you need a license for that particular use. For example, if you want to add the music to your movie (series). Many of Alex Ruis' pieces of music were created for use in numerous productions by others.
If your budget allows, you may also be interested in having music specially produced for your product. Please contact him for that.
