Here are my sources: (in order of reliability)

• Last.FM / Pandora Internet Radio – I suggest using Last.FM because it’s more social. You can see what others listen to. Here is my Last.FM
• Spinner CD Listening Party or Aol – These are AWESOME. They are a good way to listen to full CD’s before they are released.
  A good way to expand your ears.
• NPR Music – All Songs Considered – Song of the Day, Concerts, Interviews are an awesome source of new music information. Plus they are really cool and funny.
• Metacritic – Takes a bit of searching, but a great place to see what is Acclaimed.
• Best of …. Lists – It’s always good to hear what others liked last year. Chances are, you will like it too!
• Billboard - I go here when I want to find pop music. It beats listening to top 40 radio.

Then, when you find music. Buy It For Cheap On Amazon (Current Bestsellers)!
