I'm adding this from the thread in the hopes that it might help someone else -- it helped me and worked perfectly! Thank you Michael!
Note to all: the "iExplorer" mentioned in this copied text is a free program -- Google it -- and worked like a charm. However, I am not the initial author, and make no claims as to whether or not this will truly work for you.
The iExplorer method worked for me as well, with a few slight modifications.
iTunes Match stopped working on my iPhone 4 (Music app would either show 'No Music' or a cloud icon w/ a blue progress bar that would barely move). Toggling iTunes Match on and off did not help, nor did syncing with iTunes on my MBP. I wanted to avoid a factory reset but I was pretty sure some core music library files were corrupted.
I determined that I did not have to delete the entire 'iTunes_Control' folder to get Match working again. I used the following process:
1. connect iPhone, open iExplorer
2. navigated to iPhone\Media\iTunes_Control\iTunes
3. copied these 3 files to my desktop:
4. deleted the same 3 files from my iPhone
5. performed a hard reboot on my iPhone (home button + sleep/wake button, hold until you see the apple logo)
The reboot forced iOS to recreate the 3 MediaLibrary files. After this, I was able to turn iTunes Match on and my entire library showed up on the iPhone. I am able to redownload tracks as needed now.
Thanks for the suggestions in this thread, they were very helpful.
