The use of titanium in music is becoming more and more popular, as more and more artists discover the unique possibilities that it offers. In addition to Rihanna and Sia, many other famous singers and bands have worked with titanium artists to create one-of-a-kind soundtracks for their music videos and major motion pictures. Some recent examples include Lorde's 'Royals' video, which used several pieces created by titanium artist Tristan Eaton, as well as the soundtrack for the movie 'X-Men: Days of Future Past', which featured several tracks composed using titanium instruments.
