🎯 WHAT WAS FIXED
|
||
|
|
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
||
|
|
|
||
|
|
Problem: Profile songs took 5-10 seconds to load
|
||
|
|
|
||
|
|
Cause: N+1 query problem (made 1 API call per song)
|
||
|
|
|
||
|
|
Solution: Optimized to fetch all songs in ONE query
|
