# Song Tier System

All songs on the platform are automatically classified based on their total number of plays.\
This tier system goes beyond simple statistics — it serves as a visual indicator of each song’s popularity and reward level within the ecosystem.

#### **1. Tier Criteria and Classification**

Each song is automatically assigned a tier according to its accumulated play count.\
Daily reward limits (MIC) vary depending on whether the song has been issued as an NFT.
