Judge: Trial needed to solve "Blurred Lines" case

A U.S. judge says a trial is needed to determine whether the hit song "Blurred Lines" copied Marvin Gaye's music.

The ruling Thursday by U.S. District Judge John A. Kronstadt says there is a genuine dispute about whether the song by Robin Thicke and Pharrell copied elements of one of Gaye's songs.

Thicke and Pharrell have been fighting with Gaye's children in court for more than a year. The song was one of 2012's biggest hits.

Thicke and Pharrell sought a ruling that "Blurred Lines" did not infringe on copyrights to Gaye's song "Got to Give it Up."

The Gaye family also claims Thicke improperly used Gaye's "After the Dance" for his No. 1 R&B hit "Love After War."

Kronstadt ruled a trial was also needed to decide that issue.
