Hi, I'm trying to get to level 39 but I still don't understand the experience system, I understood that completing the same song in different difficulties gave you the xp as if they were different songs but apparently it's not so I ask what is the fastest way to level up? Thanks :D

Hi, I already have the achievement for getting 100 songs on perfect, but I don't understand why I only have 87 for the "Complete 100 songs" achievement. Can't you repeat songs for this achievement, or what's going on?
