I have MANY songs that for some reason didn't tag right when they were imported to Limewire. There is a number, the name of the song, the time, but no artist info. When I change the info, half of the time it deletes the time information, doesn't add the information that I changed, and it's as if the song is gone, even though the name is still there. I have tried deleting them from the library and then re-importing them, but they come back the same way. No time, won't play. These are my own cd's from my iTunes account.
