If the company culture is to listen to techno and drink beer, then sure. For that company you wouldn't be a culture fit if everybody else is going to bother you by doing these things. More important parts of culture could be, say, a reverence of quality, or being nice to people. If a candidate is an asshole, that would fly at some companies, and not at others.

It's not discrimination because one could choose to not be an asshole, or to develop an appreciation for techno. Discrimination is when you don't hire somebody because they were born differently than you, not because you don't get along.

You could try to spin not hiring people who like techno as discrimination, saying they were born not liking techno. You might be able to bend the definition to fit, but I doubt we'll ever see legal protection for people who don't like techno.
