13 is the eighth studio album by Die Ärzte, counting "Debil" the first, released on May 25, 1998. It's their most successful album. The 13th track, "Männer sind Schweine", is their most successful single.
The CD version of the album features a hidden track in the pregap of the first song. This technique has been later used frequently - on Geräusch, Jazz ist anders, Farin Urlaub's Am Ende der Sonne and Bela B.'s Bingo. On vinyl versions of Jazz ist anders and Am Ende der Sonne though, the hidden tracks aren't lost, but put after the last track.
The album features a large amount of film and TV samples. Samples are used on tracks 1, 4, 5, 8, 10, 12, 13, 16 and on the hidden track.
A promo single titled "Eine Botschaft von Die Ärzte - In Stereoooooooh!" was released in 1998. The title track "Eine Botschaft von Die Ärzte" (A message from Die Ärzte) is a kind of a commercial for 13. It also features "Goldenes Handwerk" as the b-side.
"Nie wieder Krieg, nie mehr Las Vegas!" also goes by the title "Hütchenspiel" (Shell game). "Nie gesagt" was initially titled "Du fehlst mir" (roughly I miss you).
