Smart Playlist issue with duplicates

Hi all,

Here's what I'm trying to do: To create a Smart PlayList to display all songs I have (individually, out of their albums) arranged by Artist name.

Here's what I have:



And the problem is that I get as result *every single song* duplicated.

Things I've checked on:

- Unique Folder for Music Library
- No physical file duplicates
- No other mode (Genere, Artists, Albums, etc) shows duplicates, just the Smart Playlist

Using Frodo RC3.

Any ideas? it looks like a bug so far.

Thanks in advance!
