Sorry but could you edit out the name of the copyrighted song you're trying to download? Just that it's against the Forum Rules

Unfortunately not much music is rated with Bitzi (it should be!), people tend to use it more for rating video.

Try using the All Types search as well as Audio. Look for artist or album name rather than song title. The fake files used to be most common with new releases but it seems like they're appearing with searches for older files too
Stay away from the files with huge numbers of sources, I go for files with 10 sources or less.
