Only a few days after upgrading 200+ songs to iTunes Plus, I went back again today, and found another almost 200 songs to upgrade. The biggest chunk there is the complete Led Zeppelin, which I bought for $99 a while ago, and will now cost me about $30 more to upgrade. I’ve noticed that the songs are downloading pretty quickly, but the bit where it says “processing file” right after the download is taking quite a long time on each song. I have no clue why that is, but whatever it is, it’s going to take a long time to get all that Led Zep converted to iTunes Plus.
