One of the drawbacks of digital downloads is that it is harder to repair a song when there is an error in the MP3. I just purchased a few albums from Amazon last night, and one song has what sounds like a skip 1:45 into the song. If I had recorded it from CD or LP, I could just rerip/rerecord the album. With a digital download, I have to contact Amazon, get a refund, and then either take my chance replacing the song from a competing service (such as CDBaby or iTunes), or order the physical CD (which means I end up spending more money).
As an aside, the iPod is up to 25191 songs.
