It's kind of incredible to think that artists like Squeeze are re-recording their best-known songs, note for note, without any intent to make money from their fans but instead gain more control over publishing royalties.
"Soundcheck" does a nice job of looking at why artists are doing this, and how some fans get hoodwinked into buying something that isn't truly original. At least Squeeze, tongue in cheek, named its new greatest hits collection "Spot the Difference."
