The Maratone production crew now consists of producers/songwriters Max Martin, Rami Yacoub and Arnthor Birgisson.
He has continued to use the new rock sounds on hits for Taylor Swift, Pink, Katy Perry, a-ha and many more.
Martin eventually evolved from Maratone Studios to found and operate his own globally successful production companies, such as MXM and Wolf Cousins[2][3] and has gathered numerous working affiliates, making themselves a songwriting and production collective under the label.
Songs recorded at MXM Studios include "Stone Cold" by Demi Lovato, "Birthday" and "Roar" by Katy Perry, "Scream" by Usher, and "Let There Be Love" by Christina Aguilera.
In 2013, the production entity Wolf Cousins was created in Stockholm, with songs such as "Cool for the Summer" and "Confident" by Demi Lovato, "First Love" by Jennifer Lopez, and "Problem" by Ariana Grande being produced in the Wolf Cousins Studios.
