I think you misunderstood me. My column layout already looks this way:
The reason why I ask for a function that sorts albums by its rating is that the column field doesn't calculate correctly.
Example: album #1 has 36 stars / 11 songs = 3,27 stars per song, but album #2 has 30 stars / 9 songs = 3,3 stars per song,. The arrow of the album rating field in column is down. If you could make the album calculation more exact I would be happy. It's one thing I really miss since moving from MM to MB. On the other hand the first screen I did post in this thread, the calculation there works fine, but the layout, as stated, is annoying.
