"Red" touches on Swift's signature themes of love and heartbreak, however, from a more mature perspective while exploring other themes such as fame and the pressure of being in the limelight.  The album features collaborations with producers and guest artists such as Gary Lightbody of Snow Patrol and Ed Sheeran and is noted for Swift's experimentation with new musical genres.
