Major news agencies usually have "music" sites where you can select through the artists they think you should hear. Naturally, almost none of these include Burzum, and they'd be horrified to include it.
Example:
http://www.bbc.co.uk/music/From this comes an idea.
Theory: They are collecting data to see what people are willing to buy, as well as trying to shove it down our throats.
1. Collect list of major music sites with search blanks
2. Create script to search repetitively for variations on 'Burzum' and 'Ildjarn;
3. Have fifty or more dedicated Hessians apply themselves to this task.
Consequences: we may never know, but it's possible they will at least experience great consternation and make hilarious public statements about evil black metal. At best case scenario, they'll start selling Burzum via mainstream record sites, which is no loss as black metal is already dead, so we might as well market what could positively influence the hordes.
