(WOLF) -- Spotify is facing a $1.6 billion lawsuit, accused of violating U.S. copyright laws.
Wixen Music Publishing says Spotify used more than 10,000 songs without a license.
Those songs include Tom Petty's "Free Falling," and others by artists like The Doors, Neil Young, and Missy Elliot.
U.S. law requires two copyrights for every song, one for the actual recording and one for the composition.
Wixen says Spotify did not get the composition rights, and they're seeking the maximum-allowed damages of $150,000 per song.
Spotify has not commented.
The music streaming giant is also facing three other lawsuits, and has already paid $43 million to settle a similar lawsuit in May.
