I signed up for iTunes Match a couple of weeks ago and it works great. Keeping my PC, my MBA (2011) and my iPhone synced up with my music has never been easier. I have a few albums I personally ripped and were matched successfully (192kbps constant MP3s). To save some space on my MBA I deleted the MP3s and attempted to redownload the Matched AAC version (since they were matched) of songs that I play more often. The songs that were downloaded were my exact versions! For example, the iTunes version of one song in particular is 5:01 in length, my version was 5:13. When I downloaded the Matched version it was also 5:13. Shouldn't it be the iTunes version that I'm downloading, i.e. the 5:01 song? Thanks for any input.
