Music in New Zealand political as 'a blatant rip-off' of Eminem song, court told

The composer of the opening guitar riff for Eminem's Lose Yourself has told a court the soundtrack of a New Zealand political ad is a "blatant rip-off".

Jeff Bass told the High Court in Wellington that the song - titled Eminem Esque and used by the ruling National Party during its 2014 election campaign - sounds like "Lose Yourself Lite".
