Have you seen this movie? 
It's such a quiet (unassuming) film. It really snuck up on me. I wanted to mention it here because it definitely falls into the category of all things creative and inspiring. The first scene in which you see the main characters (played by Glen Hansard & Marketa Irglova) sing/play together is captivating. It's so simple, but powerful. The way their voices blend, the delicate way the scene unfolds into the beauty of the song. Amazing. I couldn't get the soundtrack out of my head and now, several weeks later it's still in my regular rotation.
Someone else inspired by the music in this film put together a video of the song The Hill along with vignettes of people answering the question "What does it feel like to be in Love?" The clip is worth a look, as are the many great answers to that question that people have posted below it.
How would you answer the question?
