Add me to the list of "stuck" matches. Last week when it first hit, I was able to get my library of ~2300 songs to go through and finish, though the majority of them weren't matched, even though they exist on iTunes, so at the moment, if the matching doesn't improve, I've paid $25 for cloud storage of even my crappy tracks I was under the impression would match and I could redownload as 256k AAC's. The downright funny thing is, I have albums where half the songs got matched, and the other half did not. Now, for the last 3 days, I can't get iTunes Match to get past step 2 with 18 songs remaining, and since theres no diagnostic info, I have no idea what these 18 tracks are that are stalling the process.
