Trouble adding an album in iTunes - No artwork and brackets ( ) in the album name

This nearly drove me mad !

I wanted to add a previously ripped to MP3 album to iTunes.

I keep a copy of MP3s for iTunes apart from my main MP3 collection so I checked the tags were fine (using ID3 Tag edit) and copied the files into the appropriate folder.

Added the files to the iTunes library and no sign of them.

I looked down the bottom of the list and after the "z" artist, there they were with no metadata.

I corrected this using the iTunes editor and added the artwork. This took a couple of goes but seemed to work.

I synced with my iPhone and..... NO ARTWORK !

So, what was odd about the MP3s ?

I found a different cover JPEG, that didn't help.

Deleted and re-imported the MP3s, that didn't help.

After a day I started to wonder if the fact that the album title had brackets could be a problem.

I changed the album title removing the brackets in ID3 Tag edit and imported again.

No good.

Then I looked at the file names in Windows, that still had brackets in the "advance data" so I deleted that and imported again.

SUCCESS !

Correctly imported, recognised the tags and the album artwork takes and transfers to the iPhone.

It seems that iTunes has a problem with album titles with brackets (Parenthesis)  in them.
