After I have matched my library to iCloud and have downloaded the new, supposedly better, files, many songs do not play completely through on my ipod. Why?

Question

So, I signed up for Match because I wanted to upgrade my music files and replace broken, incomplete ones with clean, reliable ones from Apple.  Out of 16,660 songs in my library, only 648 weren't matched, which is just under 4%. I consider that to be pretty good, especially since I have a lot of covers and less popular music.  BUT, now after going through the Match 3 step process (which took a week the first time), deleting my original files and replacing them with the supposedly better files that were matched, I now have many songs that are not playing all the way through.  Now, here's the weird thing:  I deleted the offending songs from my iTunes, downloaded another copy of the file (which may or may not have been from the original source) and matched the newly downloaded files to Match.  When comparing the newer, upgraded Match file to the supposedly identical older version, most, but not all of the time, the newer version is several seconds longer than the old one.  This makes sense since the ones that play incomplete generally stop a few seconds before the end of the song.  But, this process of deleting and replacing songs is a pain, especially with the need to go through the upload/download process.  So, here's the thing:  I thought that the matching meant Match was matching my songs to the same songs in the iTunes store inventory.  So, how do I end up with different lengths????  Especially since these are the files in the Cloud, not the ones I downloaded.
Judging from the many blogs I've read, this song cut-off issue is prevalent and, it appears, Apple hasn't seen fit to address it.  So, is there a fix, other than the process I go through?
Thanks!

Your milage may vary, but while downloading select Downloads in the left-hand column and make sure Allow Simultaneous Downloads is unchecked. This seems to help with partial downloads...
