What defines a classic? In the case of yesterday's Classic Pack release for Lumines Supernova, it seems that truly classic skins from the original PSP game, such as "Shake Ya Body," "Lights" and (perhaps saddest of all) "Shinin'" have been omitted. In fact, it contains no songs by Japanese artist Mondo Grosso, who contributed to Lumines and Lumines II.

We've contacted Q Entertainment regarding the omissions, in an attempt to get to the bottom of why these songs, in particular, were left out.
