Pandora

I love Pandora. This site actually works very well. Everyone may already know about this...but I had no clue it existed. You can create stations on Pandora, and it will search for other music that you may like based on the artist and the genre. It works very well if you are in a certain mode & mood. You can have a Sarah Mclachlan station, and a...a.....I don't know, something opposite of that, lol. ummmm maybe Lincoln Park or Sublime.
