The bars where they show the connection is blue, and will not allow me to download any songs. what does this mean?

Blue connection bars mean that you have a turbocharged (very good) connection

What happens when you try to download?

When you click to download, do files move into the download pane? If not, try the advice here
License (click)

Or, do files sit connecting for ages & then get stuck needing sources forever?If that's the case, you're probably seeing fake files.

If you're searching for music files, use the All Types search & search for artist or album rather than song title. Go for a file with 10 sources or less...stay away from the files with huge numbers of sources.
If you're searching for video files, always chech the file with Bitzi before download. If a file has heaps of sources but no Bitzi rating, chances are it's a fake.

Check out the threads below for more info & tips, including how to use Bitzi
