RADION uses Creative Commons licenses to enable the free distribution of an otherwise copyrighted work. CC licenses all grant 'baseline rights', such as the right to distribute the copyrighted work worldwide for non-commercial purposes, and without modification. Artists choose a license according to the conditions they want to be applied to the song. The details of each of these licenses depend on the version, and are made up of a selection of four conditions:

Attribution (BY):

You can copy, distribute, display, perform and remix this work as long as you credit the artist’s name.
It means that you can use the song for anything, as long as you mention the name of the author of the song in the description or credits.

Non Derivative (ND):

You can only copy, distribute or perform verbatim copies of this work but you are not allowed to remix or modify this work.
It means that you can’t use the song in a video or for any derivative work, like a remix for example.

Share Alike (SA):

You can distribute the whole work or the derivative work by re-using the same license.
This means that if you use this work on a video or in a remix, you must distribute your own work under the same CC license as the song itself.

Non Commercial (NC):

You may copy, distribute, display, perform or remix this work, but for non-commercial purposes only.
For example, you can’t use this work to do a monetized video on Youtube or in a video which is promoting or advertizing something. However, if the video is not for profit or monetized (if it's your personal holiday video, for example) you can use it.
