I'm not sure if there are other governments that are "forcing" regulation on music retailers. Not in the US anyway. I know that entertainment governance bodies like the RIAA and the MPAA put a ton of pressure on the government to do what they want. They lobby and spend millions "bribing" our politicians. But seeing as we are a capitalistic country, directly regulating music sale prices would be a bit strange...although our government regulates a lot of other things that are strange as well.
As far as DRM goes, we are now seeing almost every online music retailer dropping DRM; Apple, Amazon, Yahoo, etc. because they know it's bad for sales. I've even seen reports from companies in other countries where their DRM-free tunes sell 4 times as much as their DRM crippled tracks. It's taken a good 4 to 5 years for the music companies to realize this in my country. Maybe that same thing will happen with your country.
One thing is for certain, if we as consumers don't let our voice be heard, nothing will happen. So keep making noise.
