iTunes Match is stuck on the last song in step 2 of the initial process iTunes Match has worked well, so far, except the process seems stuck on the last song. I have more than one song 'waiting', so I can't tell which song this is stuck on:

 

Console shows the (not very)helpful:

11/19/11 3:37:16.652 PM iTunes: _AMDDeviceDetached (thread 0x11302b000): Device 'AMDevice 0x7fe5afcdad00 {UDID = b40482688c52cdaa90ef21796c4dad05f445c06b, device ID = 29, FullServiceName = 58:55:ca:e3:7a:39@fe80::5a55:caff:fee3:7a39._apple-mobdev._tcp.local.}' detached.
in iTunes, select your Library -&gt; Music and then right click on the Column Headings and choose iCloud Status. Sort by this new column and the file causing the problem should have a 'Waiting' Status which you can then remove.
