Nicky - It's always an interesting question because difficult can be different form different points of view.
Enya - I think every song as a difficult stage. We work on it over 3 years, because we work on a song, set it aside, and them come back to it later and that's when you can see what you want to change. And that's how we get through the difficulties of a song. But I feel they all went through stages of difficult because looking so long on them, rewrites.
Nicky - There was a lot of work on Dark Sky Island (the song), a lot, but sometimes you have a piece that's calling out for more and more harmony and input. Sometimes that just defines a piece, and because the stars are involved, the heavens are involved - that feeling, the multi-vocals and all that, winds itself into the song.
Roma - I didn't find that one so difficult from a lyrical point of view.
Nicky - I think once you've got the melody, we're over the worst part, or the hardest part I should say. At least we think we are.
Enya - To me, that's where the time factor is so important because you're able to oversee the songs when you come to a difficult part.
