First off, what a great peace of software for tagging and making music listings, but.. now im stucked with a problem here.
Heres the situation:
I fire up Mp3tag, and import some music folders from my hard drive and also from some cd's. And here comes the problem. If i now want to add some new music folders to my previously created and saved playlist, all the songs imported from cd's are gone 
As i see, Mp3tag checks for the actual files when opening playlist files, which makes it impossible to create a 'static' playlist collection.
Or am i completely blind and missing something here? 
No, you are not completely blind - Mp3tag simply doesn't support caching of information from removable drives
