One more feature from Google. Specialized music search.
Say you enter "The Beatles" in the searchbox. This is more or less what you will get:
Notice the first result, it's not a typical one. Click on it and you will get a detaild list of all Beatles records, links to reviews for each one of them, the artist's blog (if ther is one), etc.
You may find more at Official Google Blog: Searching for music.
I like it!
