In her acceptance speech for album of the year at the Grammy Awards, Taylor Swift made a clear but unspoken reference to Kanye West, who several years ago grabbed a microphone from Swift at the MTV Video Music Awards and last week released a song with a crude comment about her and suggestion that he made her famous.

She also used the speech to address fellow female artists.

"There are going to be people along the way who try to undercut your success or take credit for your accomplishments or your fame," she said. She urged others not to be sidetracked by the naysayers and know that when they succeed, it will be the people who loved you who put you there.

Swift's "1989" also won best pop vocal album, and she won a video award for "Bad Blood."
