iTunes frozen with iTunes Match?

    Hello there,

    I have this custom setup of iTunes: I downloaded all tracks from iTunes Match, plus have a few others that weren't matched, all residing on the local hard drive.
    Since this took too much space and I intend to cancel iTunes Match next year anyway (rumors of Apple cutting off download ability and debatable match quality), I spanned these music files to a WebDAV server running on my Synology, using TuneSpan.

    All went fine except for a few tracks that couldn't be moved.

    Now, I restarted iTunes, and iTunes Match immediately started recompiling information on my library. Problem is, it seems to be taking forever. iTunes is unresponsive and displays the beach ball. Traffic on the LAN and on the server is really low, almost insignificant.

    I tried a force quit, but it ended up with a locked library file, solved by resetting permissions to read-write, read-only, read-only on ~/Music/iTunes folders and subfolders.

    Already tried: re-using an older library file: somewhat works in the sense that tracks are still shown, in their mistagged state, but fail to play because iTunes doesn't know where to look for them. Of course I can't possibly manually re-point all tens of thousands of entries to the correct file on the webDAV server.

    How would I get iTunes responsive again?
    Maybe preventing it to compile information about my library?

    Backup the library and don't point iTunes to it. Reboot and launch iTunes. You should see your music with a little cloud next to each track. If you then wish to point your iTunes to your files then by all means do so but you'll need to delete the library file and allow it to recompile the whole lot.

    You mean backup the ~/Music/iTunes folder and subfolders? Or the webdav/Music folder? Then re-download everything from iTunes Match? This part isn't clear to me.

    And how would I "un-point" iTunes from its library? Currently, iTunes trying to scan library for iTunes Match happens so quickly that I don't have the time to change settings.

    Default media library is still the local one, only most tracks are now spanned.

    What is your hypothesis on the origin of the malfunction¿?
