Google Music Search offers links to download songs but only off of a select few major stores like iTunes and Napster. I want to buy independent music from Magnatune and other online stores. Google really needs to make this more open.

Yes, favours well established download sites. Anyone heard anthing more about http://www.spiralfrog.com/

Magnature IS well-established. It's just not as big as iTunes and Napster.

I'm surprised they've never really done anything else with the Music search, doesn't seem like they've done anything to it for a while. Apart from including links in normal searches, but this has been happening for a while.
