Korean tracks show highest average popularity (27.55/100)
English dominates volume (23,392 tracks, 37.5% share) but has optimization potential
Emerging markets (Hindi, Malayalam, Telugu) show significant growth opportunities
🏭 Audio Feature Portfolio Analysis Energy shows strongest positive correlation with popularity (r=0.148)
Danceability and valence have moderate positive relationships
Acousticness demonstrates negative correlation with popularity
Identified optimal feature combinations for different language markets
High-popularity outliers (2,888 tracks) are 5.0x more popular than average
Key differentiators: +0.040 danceability, +0.083 energy, higher tempo (120.6 BPM)
Significant potential for replicating successful patterns across languages
Energy optimization identified as primary lever for popularity improvement
Danceability balance crucial across different language preferences
Tempo variations show market-specific optimal ranges
Historical analysis from 1971-2024 reveals evolving musical preferences
Recent trends show popularity score variations year-over-year
Production patterns indicate strategic release timing opportunities
