Many thanks, Limnos and Gail. 🙂 I'm disappointed that Apple doesn't offer another method to upgrade. I upgraded many of my songs at the time it was offered originally, but since I had well over 1200 purchased songs, it was financially impractical for me to upgrade all of them over the time period it was offered, even at 30 cents a song.
As for the interest in upgrading now, it's partially to remove the protection and partially to get the better quality sound that the 256 Kbps iTunes Plus songs offers. I could burn the songs to CD, it's true, but since I still have about 1000 songs that are protected, burning roughly 20 at a time is a little impractical, and of course, as you mentioned, you lose sound quality when you reimport the songs from the CD.
And as for why I don't want to use iTunes Match, I don't want to do that because, as I understand it, when you utilize it (and when I upgrade the protected songs to iTunes Plus), you lose the metadata that you might have set in your files when you replace them with Apple's. Is that correct, or is that a misconception on my part? I've spent a LOT of time curating my library and getting the metadata for my songs set the way I want it, and many of my smart playlists take advantage of those settings, and if possible I don't want to have to redo it. With an overall library of over 8000 tracks, that would be a real headache. 😉
Any other thoughts or suggestions about what I might be able to do to remedy this situation? Thanks in advance for any advice you might be able to provide.
