Haha I've spent all day poking around on music sites. But I found an awesome band in my JPOP search. BUMP OF CHICKEN! First of all - that name is full of greatness hahaha. They've apparently been around since the 90's, but I've never heard them before. I really like the lead singer's voice (he wails!), and I absolutely LOVE this song.
And big props to Jesse for knowing that I would love this band, Owl City. The second I heard them I was smitten! The music sounds a lot, I mean A LOT, like The Postal Service...which seems to cause a lot of people to hate this guy but I don't care. I loved The Postal Service, so whatevs.
(Can't embed the read music video, but this song is still win)
