I'm afraid there are a lot of these results and the junk filter now built into Limewire is useful for filtering them out.
If you neeed more help please let us know, but personally, I vary my search terms and the type of serch I make and find that I can usually get results without too much rubish. I gonore anything under a few MB unless you know you are looking for a very short track
I hope this helps
