I quietly support one non-popular music site. One of the features of the site is the publication of song compilations with the consent of the authors. The first part is now walking around the network, half a year later, announced a set in the second. The collection is distributed only online, free of charge under the Creative Commons Attribution Non-commercial No Derivatives (by-nc-nd) license.
The set-up began, the first applications went and one of the groups sent a cover version of the song of the foreign author. Can I use this song in the collection?
