Comment 7 for bug 673237

I'm not sure but touching every file to check it is missing when we add a list of files to a specific crate. That sounds like we would hit a huge performance hit when all we want to do is a simple sql query.

As for AutoDj. It should handle the missing tracks gracefully. We can never relly on track in the autoDj playlist being still available (that can change between the time it was added and when it is supposed to be played).
