Upon their return in 2000 with the album "Room Service", Adams produced the album and co-wrote the songs with various co-writers, the themes of the songs being varied between street life, touring, truth, love and relationships. He again opted for a rock-oriented sound. In 2008, with "11", produced by the same Adams with the collaboration of Mutt lange, he sees the return of his long-time collaborator Jim Vallance after more than 15 years, he has experienced a sound softer, combining songs from soft rock, pop rock and melodic rock. With "Get Up" produced entirely by Jeff Lynne, they continued in the line of rock, with the strong influence of Lynne's fifty-year experience. Adams has always felt the album like the album he would have wanted for so many years. In 2019, with "Shine a Light", he combined rock with pop rock and R&B.
