Music: Title by Shane Ivers - https://www.silvermansound.com
Just replace 'Title' with the title of the track you're using, simples! Please don't remove the URL. The URL should also be a hyperlink, not just plain text wherever this is permitted please. For YouTube, Vimeo and similar, I prefer you include the credit and link in the description where possible.
As long as clear credit it given, you're covered to use these songs for free under the Creative Commons Attribution 4.0 International License.
If you're wanting to use a track in a format that can't display a web-based credit (e.g. TV, Games & Radio), you can include the credit in any way the viewer can clearly find. If you cannot do this, you must purchase a non-attribution license. I charge $20 per song per project for these, and you can find a link to purchase one on the song's page below the description.
