Adding MP3s to iTunes 10 doesn't work for some files I have recently upgraded to iTunes 10. I had some MP3 files which I would like to add to the library. In the past I have dragged the folder into the iTunes "Library" section which has added all the songs, but this time it only added the last two songs of a ~20 song album. Adding the files individually does not work either, and "File > Add to Library" does the same thing (only adds two of the songs).

Is this a known issue, and is there a workaround?
In many cases, improper tagging causes the files to go weird places. I suggest you create a smart playlist that shows you “new added” stuff:


I usually have the same problem with mp3 with dubious tagging.
