iTunes Ripping - Strange Digital Artifacts

I've tried a few variations on archive searches and wasn't able to find an answer to this: In ripping some of my CD's into iTunes (either Apple Lossless or WAV) I've been getting some very odd, brief digital artifacts at the end of each songs on a CD. This sounds like two or three seconds of an audio tape on fast forward. It only seems to happen on new releases (I cannot think of any older CD's it's occurred on). I just got a copy of Mary Gauthier's new album (great CD by the way) and it happened on that one. I tried ripping it multiple times in Apple Lossless, and WAV (always in iTunes) and each and every time it created files where this strange artifact existed at the end of every song. I play the CD I ripped the files from and the artifact is not there. Is this some kind of anti-piracy technology...or do I simply have some setting off in my itunes preferences (Error-Correction is on, WAV or Apple Lossless is always set to Automatic, have experimented with importing to startup disk and external disk-same results). The artifacts seem to always sound the same too...they never vary, except that they sound different from song-to-song, but the same if say, the first cut is played over again.

Anyone have any clues what this might be?
