In 2014, Marshall Bruce Mathers III, known by his stage name Eminem, filed a suit against New Zealand’s conservative National Party for copyright infringement. For the party’s 2014 election campaign ad, it copied Eminem’s 2002 hit song, “Lose Yourself”. The party says it purchased the track, titled “Eminem Esque”, from an Australian-based music stock supplier. Although the party claims it would never use an unlicensed song in a campaign ad, email exchanges between party agents show that they had some concern for the song they described as an Eminem “sound-alike”. The judge-only case is ruled by Judge Helen Cull and is expected to last about six days.
