I hadn't had time to do much research on this because my head's been in other projects, but after some tests this morning it really looks like there is a bug with adding new artwork to tracks in iTunes 10.4 running under Lion. Perhaps this is old news for some. I've been getting various email reports of this, but no one ever has the same story, which makes it difficult to piece things together. The problem seems to be: while new artwork will display in iTunes, it does not travel with the file (eg, when copying to another Home Shared iTunes) nor does the Finder icon of the track's file display the artwork. Seems like the image data isn't being written to the file. Doesn't seem to be a problem with iTunes 10.4 in Snow Leopard, though. There's no homemade fix that I am aware of so we'll have to wait to see if Apple does something about it.
Obligatory post for the record: iTunes 10.4 is available, optimized for Lion--yes, that means it's 64-bit Cocoa!
Apple released iTunes 10.3 which has the new iTunes in the Cloud feature that will be a part of iOS 5 and OS 10.7 Lion later this year. Auto-downloading and re-downloading of purchased content to your various devices is enabled.
I often have to add files to iTunes that I've received as mail, iChat, or Skype attachments or from other disparate sources. They're usually audio files that friends or colleagues have generated and aren't necessarily song files. They usually don't have any ID3 Tag info other than the file name/track name. I just drag 'em to iTunes, select a batch after they're added and multi-edit their tags. But somehow this workflow doesn't feel right to me. If I were ripping a CD, I'd enter the tags in the CD tracks before importing. Likewise, when I use PDF Adder I'm obliged to enter any tag info first.
But when I'm importing the files from the Finder I can only edit the tag info after the files are added. Thus, I have to find them in iTunes, select them, press Command-I to get the multi-edit window, and then I can start tag editing. Doesn't feel right.
So I put together a droplet called Drop to Add and Give Info that launches a GUI for multi-editing after you drop files on it but before the files are added to iTunes:
iTunes 10.2.2 fixes a few problems with iOS syncing and has some obligatory stability and performance enhancements. Download it directly or hit up Software Update.
This afternoon, Apple posted iTunes v10.2. According to the Apple blurb it mostly provides accommodation for iOS 4.3.
I've been hearing from Correspondents that the half-stars they had meticulously set in their track ratings have disappeared. I think one of the v10 updates wiped out the half-star preference or something. Anyway, you can bring back the half-stars by doing the Terminal thing (quit iTunes first):
defaults write com.apple.iTunes allow-half-stars -bool YES
Or you can use Change Hidden iTunes Preferences which has an option to toggle 'em.
