I have a playlist in iTunes that shows all my songs that are matched with iTunes Match but are lower than 256 kbps. What I do every once in a while, is delete all the songs in the playlist (I delete them from iTunes, but NOT from iTunes Match/iCloud, then download them again. This is supposed to download the 256 kbps copies that iTunes has of each song.
Lately though, I've noticed that when I delete and download these songs again, the version that is downloaded is exactly the same as the one I just deleted. Is this a new thing? Or is this just a bug?
