Spirit is filing an appeal after losing their case against Led Zeppelin.  

The band sued last year, claiming Zeppelin stole parts of their song "Taurus" for "Stairway to Heaven." Attorneys have asked for a retrial on the grounds that the judge would not allow "Taurus" to be played in court, forcing the jury to use sheet music to reach the verdict.  The jury unanimously ruled in favor of Zeppelin last June saying there were no substantial similarities between the tunes.

What do YOU think - ripoff or BS?!
