How is the 161.b file in Gracenotes example project GN_Music_SDK_iOS project created and how exactly is it used?
The application is running fine after deleting the file. It does not get recreated.
How is such a cache file supposed to look like before its first usage? Simply an empty file?
It is a seed file with fingerprints and results supplied by Gracenote. It is distributed with the SDK, and does not get mutated during the lifecycle of the application.
