Nena feat. Nena, also known as 20 Jahre – Das Jubiläums-Album (20 Years – The Anniversary Album) is a studio album by German pop singer Nena. It contains new versions of her hits, many with her band also called Nena, some of them duets with other singers including Kim Wilde, Joachim Witt and Udo Lindenberg. The album was first released in 2002 with a red cover and reissued with a blue cover in 2003. Both releases exist in either standard or limited edition, the latter being supplemented with a bonus CD of live tracks. The songs on the bonus CD are also reworked, suggesting that Nena may have planned to update more of her back-catalogue, although there have been no further releases in this vein.
