In case you haven't heard, the new album is streaming at www.redhotchilipeppers.com. Click the red asterisk where London is to listen, not sure if others are working yet. It doesn't matter where you're from, I'm in Boston and listening to the London channel. If you still have trouble, I heard you can stream through RHCP's iTunes page.
My favorites so far are Look Around, Did I Let You Know, and Goodbye Hooray. I haven't heard anything past Happiness Loves Company yet, nor have I heard Monarchy of Roses or Brendan's Death Song.
