What was the title of Prince's 2006 album?

The title of Prince’s 2006 album was 3121.

Released on 21 March 2006 by NPG Records and Universal Music, 3121 was Prince’s 31st studio album. The date itself echoed the title: 3/21 matched the American release date, a characteristic piece of numerical wordplay in Prince’s catalog. The title also referred to the address of a Los Angeles home he rented, 3121 Antelo Road.

The album marked a major commercial high point after the renewed attention surrounding Musicology, released in 2004. It entered the US Billboard 200 at number one, selling more than 180,000 copies in its first week. It was Prince’s first US number-one album since Batman in 1989 and the only album to debut at number one during his lifetime.

Its songs include “Te Amo Corazón,” “Black Sweat,” “Fury” and “Beautiful, Loved and Blessed.” The title is commonly mistaken for a year or a catalog number; it is generally pronounced “thirty-one twenty-one.” Prince later used the number in promotional details, including £31.21 ticket prices for his 2007 London shows.
