It is a relatively new band, but every time they release a new single, it becomes a #1 hit.
If you have STAR World Asia on your cable subscription, nowadays you can hear them on the Heroes season 3 trailer. The background song is by Nidji, called "Shadows". This is the second time that their song has been used by STAR World as the background for a Heroes ad. Previously, their song "Heaven" was used.
