Glen Hansard, Marketa Irglova - Falling Slowly

I've heard multiple songs by Glen, and I'm pretty sure I've heard this song above as well.
This particular song was featured in the movie "Once", in which Glen appeared in the main role. While reading the novel "The life list" by Lori Nelson Spielman, it struck me by surprise that this movie was mentioned, I was amazed because the day before reading this particular part in the novel I was listening to the song and went to IMDB to read about this movie, and it was a nice coincidence! I often encounter such coincidences, ok not often, but I do encounter and these situations still amaze me.
