Try searching for 'joe', 'microsoft' or 'starbucks' (without the apostrophes) and you'll see some extra tabs above the search results.

For 'joe', you should get the following tabs:
All, Songs, Album, Lyrics, History, Influences

Wonder if they use Google Co-op for the tab categories..

very cool:) funny, if you search Google, it won't do the same thing as with other companies (like microsoft)

<<if you search Google, it won't do the same thing>>
It does if you search "GOOG" though
