I see ... thanks. Added to mantis as 14616.

Yea, that seems to be it, the albums summary within the collection does not honor the collection criteria. Track listing does.

Not sure how I can explain it any better, but this is first time playing with this Alpha version, I'll uninstall and try some more. I have a music library populated with two network folders from my NAS, one with MP3s and one with Flac. From that library I usually create two collections, one with flac, one with MP3. When I select albums in either, the flac and mp3 songs show up in both collections album views. Will start over and play around some more.

Hi.

I'm not sure i understand ? What exactly doesn't work for you ? I've tried to create new collection with 'extension equals to flac' condition and it works just fine (all tracks shows just flac tracks).

Are they supposed to work? I used to organize collections by extension, mp3 vs flac, don't seem to work. Pick album in my flac collection, I get the flac rip from CD version and the mp3 normalized volume version, etc.
