Ah right, we'll get those translations done soon, thanks for pointing them out.

These titles were just copied off the official track listing on the official webpage, but to be honest we don't really know- We've tried searching online and even the Japanese people have no clue. We've come across some blogs that theorize that LM could stand for "LoveLive! Music No.xx" but we can't be sure. It is likely just some code that they used during production to cue which music goes where.
