Searching vs Browsing - How to not browse something

[Fritz]

Good afternoon,

First of all thanks to Simon for putting all the work and ingenuity in making MinimServer.

For a number of days I am circling around the question how to facilitate browsing through / discovering music not having a certain tag value.

Concrete case is that I have a lot of classical music but not everybody in the family shares my preference. So I would like to be able to browse through albums where the Genre is not "Classical". The hard way of doing this could be to add a tag with a "Non-Classical" value. But this is quite awkward would be the last resort only.

Any ideas?
