In the spirit of the upcoming holiday!
As the title implies: please post the titles (and maybe youtube links) to some of your favorite japanese love songs: they could be from shows, bands, anything as long as it's nihon-jin. >D
Two of my personal favorites:
"You're The Only" - Galneryus
"Forever Love" - X Japan
Lol, the second one's rather emo, lol. But, it's still pretty.
