Thanks. Unfortunately that barely works for me. If I add the CD's tracks to the Library, then ...
(1) ... open the Library node to its Locations, and under that pick "CD: audio CD (F:)", right click it and select "Get album info from Freedb", it gives me the error message "No audio CD was found. Please insert audio CD." (Even though the CD is still in the F: optical drive.)
(2) ... if I instead select the MyComputer node, and the F: drive under that (where the CD is), then right click it and select "Get album info from Freedb", it just blinks at me ... i.e., the screen flicks for a nearly imperceptible fraction of a second, but nothing else happens. (It doesn't even download the track info briefly only to lose it soon after, as it had been doing.)
(3) ... But if I click on just the Library node, then sort the list of every song in the library to find just the anonymous tracks I just added to it, then right click those selected tracks and click on "autotag from the web" I get a pop-up window -- which with a fair amount of trial and error -- can sometimes find the right album, and download the track (& album) info. And that seems to stick around while I rip the music. But I got two errors for two tracks during that process, which have nothing to do with scratches on the CD:
(A) "Cannot delete C:\Users\__(my_user_name)__\AppData\Local\Temp\4B92.wav. Access is denied. The file may be in use or you may not have access rights."
(B) "File (path and filename) not successfully created."
I retried various ways to rip those two tracks, but same errors resulted. So I closed MMg, reopened it as Admin, and downloaded the track info just fine, and ripped them no problem. I also noticed that the track info I got from method (3) above (which came from Amazon) was not ideal: no track artist, no genre, and the album artist title was a paragraph (which makes for annoyingly large folder names), and the album info, which MMg put in the comment field was interesting but was several paragraphs long (so something I might not want on all tracks I rip).
In total, the option of running MMg as admin seems way preferable. It works, with the one drawback being I have to forego playlist management while ripping. Still far from ideal, but with all the quirky fails of method (3), I can't do any playlist editing that way either.
But it's sounding more and more like my troubles are atypical, so it's time to try a reinstall.
(I want my Saturday back.)
