- Open the Library.
- Choose File > Add Source Folder (or press ⌘O).
- Pick the folder that holds your music.
- Your tracks appear in All Tracks. New tracks are listed under Pending Analysis until they are analysed.
Tip. Use lossless files (WAV, AIFF, FLAC, Apple Lossless) where you can: the analysis and any stem separation work best on clean audio.
