Dear iTunes, that track with an exclamation mark is NOT missing 

itunes-exclamation-mark

As I’ve mentioned before, I keep my music on a server – not my MacBook Pro. Occasionally iTunes has a hissy fit and declares some of my music missing. But it’s not – it’s just I’m not connected to my home network. One day Apple will fix this issue (which has been around for years), but until that happens there’s an easy way to cure this… just hold down Ctrl (aka “Option”) while starting iTunes (tested on a Mac).

If you’ve landed here looking for a solution to remove real missing tracks, you can’t go wrong with Doug’s “Super Remove Dead Tracks” script.
