I think, having the possibility to force Jaikoz to individual matching would help.
 

I am sure you are right that the "complete mismatch" problem occurs very seldomly, though it depends on the data quality in the library. But as it happened with my first tests on the first files ("Accept" is at the very beginning of the artist-ordered list), I am concerned that this could happen too often.
 

I also understand the idea behind the Autocorrect feature. What I miss is an additional "interactive" autocorrect - optional, of course. So if someone does want a true Autocorrect, he still gets it in normal way.
 

Because, let me explain my problems with the current function: You say, I should review any changes made by Autocorrect. But this is very hard to do.
 

And there is no column for the length of a song (why?),
 

(By the way: I would appreciate additional columns for AcousticID-Fingerprint and AcousticID-ID, which only show whether there is a Fingerprint or ID (like in Summary tab) for saving screen space - the actual Fingerprint or ID string is an information most users won't need, I guess. Optional, of course, so the user can choose and no one gets disappointed).
 

Also I think, there should be additional columns for the "original" values from the files, without remote correction. Because to check what has changed, one has to go to the Changes tab (which is a click).
 

and then my mousewheel scrolling scrolls ~2-3 pixels down per "mouse wheel click" (not click, you know, when mousewheel snaps on next position). So it takes long time and feels horribly. So currently I have a workaround and click the General tab too see the original filename, which is the "original" title tag, because iTunes uses that information for file naming. But this is no good solution.
 

And the next problem is: lets say, I took 100 files out of iTunes to Jaikoz, and I am confident with what Jaikoz did to 90 files, but not to 10 of them. I have to select them individually (perhaps with Ctrl or Shift, but then I can't check them anymore, because I will loose the selection), and then manually "close" this files and tell Jaikoz not to save changes to these files. Click-click-click-click... and make no mistake! Isn't there an easier way to tell Jaikoz not to touch these files, when I am not confident with the lookup? Like right-click - dismiss, or a selection box in the first column which I can uncheck?
 

I tried to embed my ISRC (I was just practicing at the time) into my mp3 file. All I had to do was right click on the mp3 file & go to "properties" and I could just delete the ISRC number. Obviously I was doing something wrong...
 

I also loaded a couple of mp3 files that I downloaded legally from Amazon.com. These were both #1 hits on the Billboard Hot 100 chart. Neither song had an ISRC number when I loaded them in Jaikoz. How is that possible? Are they not being accounted for when people purchase the digital download?
