Judge tosses copyright lawsuit against Lady Gaga

CHICAGO -- A federal judge has dismissed a copyright lawsuit against Lady Gaga filed by a Chicago songwriter who accused her of stealing parts of one of her songs.

Rebecca Francescatti filed the suit in U.S. District Court in Chicago in 2011, alleging Lady Gaga had copied music and the title lyric from her 1998 song "Juda." Gaga's 2011 song is called "Judas."

Judge Marvin Aspen ruled this week the songs do not have common lyrics, have different themes and sound nothing alike musically.

The judge also concluded there wasn't enough evidence Gaga could have heard or known about Francescatti's song before publishing "Judas."

Aspen writes the songs "are so utterly dissimilar that reasonable minds could not differ as to a lack of substantial similarity between them."
