Season & VIP Pass
Season is a time-limited event that enables players to unlock in-game content at a faster pace. You can level up by earning season points, which are obtained by achieving stars while playing. For example, if you complete a song and get three stars, you'll get three season points. Rewards in season mode include Free & VIP Pass.
VIP Pass can give you access to higher-level rewards and exclusive seasonal rewards. Each season usually has three season-exclusive songs that can only be accessed through the VIP Pass. You can unlock the VIP Pass on the Season page or in the shop.
