Here's the only catch: Attribution.
Step One. Place the attribution in an obvious area, like your credits page. If it's a YouTube video, place the attribution in the description. Place it in an area where it can be seen clearly and so that it is a clickable link (it must be text as opposed to being a part of a graphic).
Please use the following attribution:
"Music by Devynn LaShure, Echo Blue Music
Simply select between the quotes and copy and paste the text where the attribution will be placed.
Step Two. Contact me when you use Echo Blue Music in your project. This way I can link back to you from echobluemusic.com.
The crucial element here is the link back to the Echo Blue Music website. You may even link back to the specific page or pages from where you downloaded the music. Such as "https://www.echobluemusic.com/collection-suspense-crime-drama" That just happens to be one of my favorite collections. This is completely optional and not at all necessary.
Now, here's the good part. Since I'm building a portfolio featuring Echo Blue Music within games, films, podcasts and really anything media related, I will link back to your site boasting the Echo Blue Music AND your project. And as we all know, links are good!
Other optional attributions would be things like following Echo Blue Music on Twitter, Instagram, liking Echo Blue on Facebook. You may even score some points there (wink wink). Social links are in the header - look up.
