I just embedded album art in a bunch of AACs and noticed that the files sizes are increasing by .4 mb greater that the size of the album art. This only happens when embedding art into multiple filesadding art to individual files seem to work correctly. I just took a 16 track album that had art embedded at the same time. I deleted all of the art and the added it to each file individually. The size of each file decreased by .4 mb! I then deleted the art and added it to the files as a group, resulting in each file growing by .4 mb. Can someone confirm this? If this album has an extra 6.4 mb, I must have several gigabytes of wasted space.
