The Xbox allows for soundstracks to be stored on the harddrive and played in-game. Music is copied from audio CDs using the dashboard and converted to WMA audio files. The notes gathered here are from decompiling StDB.dll from Xbox Soundtrack Manager.

Folder Structure
All soundtrack related data is stored in E:\TDATA\fffe0000. Songs are organized into groups of folders containing up to 6 WMA files. Zero-padded 4 decimal integers are used for the folder names, and zero-padded 8 decimal integers are used for the WMA file names. Metadata such as song title and which soundtrack a song belongs to is stored in the ST.DB file
ST.DB
The ST.DB file contains information about soundtracks loaded on the Xbox. Up to 100 soundtracks with 500 songs each can be used. Each header and struct described below is padded to 512 bytes, and all values are stored as little-endian.
