Links for Later #1 (Music)

I have a list of longer articles that I've found on the webs (with help from The Browser) and I'm thinking of putting them up here for later reading. I'll be putting them in threes with a more or less theme ..Part 1 in an ongoing series.....

• "THAT" chord on "A Hard Days Night"
• The Song Machine. It seems that hits have always been written by a small group of people who are in control of the music at a specific time. Makes me think we're being manipulated....
• Nick Cave's awesome letter to MTV
