I really love this piece - it's literally something you can have on loop to for hours without getting tired of it. There are no distracting or obnoxious sections, which is a great plus. It all seems to flow together so well, and the part when it picks up at around 2:15 just makes me want to listen to it again (I can't identify the instrument, so I'm not even going to try to wager a guess here, it'll just make me sound dumb XD For shame, since I do play the piano, and should know!).
Keep it up!
