First, Mr. Brown updated the [Doublemint "Double your pleasure"] jingle and recorded it with hip-hop producer Polow Da Don. Then, during the same Los Angeles recording sessions in February, paid for by Wrigley, Mr. Brown added new lyrics and made a 4½-minute rendition of the tune, titled "Forever." In April, Mr. Brown's record label, Jive, released the song to radio stations and digital download services as a single. After the song became a hit, Jive added it to his 2007 album, "Exclusive," and re-released the album in June. "Forever" reached No. 4 on Billboard magazine's Hot 100 chart last week.
