OK, I have just north of 16,000 songs in my iTunes library. I know that with the new iCloud, I will always be able to access them on my iPhone, but looking for something a step beyond that even.
What I would like is a database of my music and an app that could scan (via the iPhone) a cd in a used CD store and compare that scanned cd to my database and tell me if own it or not.
Does anything like that exist? Your help would be appreciated.
