Spotify’s being sued by a music publishing company that represents artists like Tom Petty, Neil Young and the Doors. Wixen Music Publishing says Spotify allegedly used thousands of songs without a license, and is seeking damages of $150K per song.

Just six months ago, Spotify settled for over $43 million to resolve a class-action lawsuit led by David Lowery (Cracker, Camper Van Beethoven) and Melissa Ferrick.
