Rain! I'm a huge fan of his. I only have his 3rd CD but his voice is really incredible. His most popular song from the album is "It's raining," but his voice on the song "Familiar face" is AMAZING. He's compared to Usher, but I think his voice is a lot more appealing than Usher. I bought his concert DVD from Yesasia. It was only $35 (compared to the $50 Japan version!!), and I really hope it arrives today. It comes with a remix CD and I can't wait to hear more of his songs.
Also, someone requested an upload of the song "It's raining" so here it is:

If you like the song, buy the album! There are great songs on it like "familiar face."
