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. This covers you to use the song for anything. Yes! Even commercial use!
Most online platforms have a text description box; this is the perfect, and probably easiest, place to put the credit. Or you can do it in any way so that a curious consumer of your content can easily find the credits if they want to see who made that most amazing song they are hearing.
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. Having a non-attribution license means that you don't have to give credit. 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. Click here to read the terms of the agreement.
