I was one of the people that signed up for iTunes match on the first day. Been very happy with the service, it matched 80% of my 10,000 songs and I've upgraded all of the matched songs to 256kbps DRM free goodness. Sadly, that still leaves 2000 songs as "Uploaded"... and most of them are 128kbps or 160kbps, some with DRM (ITMS). Since the initial release of iTunes match, a new version of iTunes has come out that's supposedly better at matching. Is there any way to force iTunes to rescan my "uploaded" content? I'd love to get the rest of it upgraded to 256kbps DRM free... or at least more of it. The difference in sound quality is significant enough that I notice when lower bitrate file comes on Thanks!
