First of all, double check you are not in a mix/compilation or label release instead of a song promotion. If you're not sure, read how to differentiate our content.
Song promotions can be used in any YouTube/Twitch, monetized or not monetized channel or stream. In the line of that, you should read how we work in terms of licenses and being safe using our song promotions (interesting if you monetize your content).
If you want to use them anywhere else, contact the artist.
Add this to your description

Copy-paste the social links of the artist (found in the description of my videos). If the song is made by more than one artist, just repeat this step. With the previous example, your description should also have:
Example of a correct description
Anyone as long as you provide credits as shown above.
