Super-awesome resource put together by Last.fm. The Campaign for Better Music, indeed! Of course, original ideas help the campaign too — don’t know if Last.fm has any advice for that.
The first time I’ve seen prices for digital downloads of entire albums for below $5. Maybe this will set a standard and bring the price of digital music down to where it should be, like back when I could buy obscure-o CDs for less than $9 at Best Buy in the early 90s.
