If the id tags on mp3s are the wrong type they will not show up with much information. You will usually get several files not fully described in any given search, but I have done a couple of searches where nothing shows up at all in the boxes on the left, which is what you are talking about, I assume.

I don't think you can do much about it except that hope that the hosts sharing the files convert the 1d tags to verion 1.1 or 2.3. I have no idea if this is really helpful advise as it is just what I have deduced on my own, with little understanding of how it works.

I can suggest that if you stasrt to d/l a file you can almost immediately preview it. Sometimes you will see the full description, and sometimes a preview number which is little use. It is worth trying though.

I hope this helps a bit!
