I would like to see a way to exclude more artists, genres, albums, etc. than what is currently offered in custom mode.

I think a simple way to do this without adding more fields, is to seperate them on the same line with a comma or a semicolon:

[argument] [catagory] = [_list]

ex: Not Artist = artist1;artist 2; artist three

Any slow-down that may be incurred to check against this list shouldn't really matter since the delay would be confined to the "Up Next" song display.

Thanks,
Rich

Here here! I think the current query builder is fantastic but with a few more possibilities (such as above) could be essential...
