Amy Winehouse won five of six categories at the 50th Grammy Awards and Herbie Hancock won the best albums of the year

It looked like it was going to be all Amy Winehouse -- until the end.

Herbie Hancock also won best contemporary jazz album for "River: The Joni Letters."

Winehouse, the troubled singer and songwriter who was let out of rehab to perform via satellite at the 50th annual Grammy Awards Sunday night, took home awards in five of the six categories in which she was nominated, including three of the big four general categories: record of the year, song of the year (both for "Rehab") and best new artist.

But when it came time for the final announcement, album of the year, the award went to 67-year-old jazz legend Herbie Hancock for "River: The Joni Letters," his album of Joni Mitchell interpretations.

The decision appeared to shock many, though Hancock wasn't caught off-stride.

In his acceptance, the pianist, who had earlier co-performed George Gershwin's "Rhapsody in Blue," paid tribute to a number of his predecessors, most notably mentor Miles Davis.
