Just found a new favourite album / group:
Kiroro - Kiroro no ichiban ii uta atsumema****a
Basically every song I hear from them is an instant hit, so why not get their compilation album.
You can get it from jps or wherever.
Special mention goes to KKBOX, the paid Asian music streaming service I use. Now that I finally have a phone that works properly with it I'm discovering just how awesome it is.
