First off - this song is a piano only, no lyrics song.
But it's still a good song.
Second off - thank you for the rising in views. It might be small, but hey - it's something. :D
Yiruma is a South Korean-born pianist who has been around and a hit since the 2000s. He is quite famous for his piano pieces. Two of his most famous ones (which I've actually played on piano before), Kiss The Rain and River Flows In You have been favorites of many.
This song is a very hopeful-sounding song. It's optimistic. I usually don't like optimistic music, but hey - Yiruma is awesome. Thus, I listen to this stuff.
And that's all.
YouTube it. That's all I can really say.
