Lunatic rave with bms preview

[TheMachine]

I often use rythm it!(for the online mode) and lunatic rave(for the graphics)
and I note some diferences, as the bms preview, in rythm it, when I have to choose a song, I can hear it before playin' it simply selecting it with the cursor
but in lunatic rave, I can't do that

i think LR is designed to be like the arcade, which doesnt have preview. that kinda sucks cuz n00bs like me dunno which songs are good XD
