A national music retailer is refusing to promote the new album from American rap singer Eminem because of its explicit lyrics.

The CD and DVD Store is not displaying the album Encore, and will only give it to customers who request it.

It is also donating $6 to Women's Refuge and a suicide prevention charity from each sale.

The retailer's managing director, Roger Harper, says he made the decision after hearing the lyrics, which he describes as violent and pornographic.

He says a "clean" version of Eminem's album will be available on Thursday.

The rapper, also known as Marshall Mathers and Slim Shady, is reknowned for his controversial lyrics, which have helped him become one of the biggest names in music.
