You're right, but due to the official SPADA OST, this is the way KONAMI name the BGM (after tricoro). Because they make the non-stop music from "card in" & "mode select" to "music select". You can find out that I separate them before Lincle.
The BG is nice, but the BGM didn't get my attention...also i'm asking myself...why konami-bemani team doesn't apply anti-aliasing to their graphics before converting them to a video format? -_-
