If you’re just coming to this song challenge or want another look at the 30 Day song list, here’s a link to the first post.
Ailein Duinn is one of the saddest songs ever. It feels sad even if you don’t know what the words mean. I usually listen to Karen Matheson’s version (theme song from the 1995 movie Rob Roy). This version by Celitc Spirit is very good, though, and it has lyrics and translation.
