The English pop-rock singer/songwriter's first hits compilation, +-=%x Tour Collection gathers two dozen of Ed Sheeran's biggest tracks in one easy package. Reaching all the way back to his 2011 debut single, "The A Team," from his first album, +, the set (also known as The Mathematics Tour Collection) continues chronologically through his career and each hit-filled studio album (including his non-arithmetically titled No. 6 Collaborations Project). Non-album tracks such as "I See Fire" (from The Hobbit: The Desolation of Smaug soundtrack) and "Lay It All on Me" (from British electronic group Rudimental's 2015 LP We the Generation) make this a solid grab for those listeners who only have his main catalog. Viewed as a single entity, +-=%x Tour Collection is an indisputable example of Sheeran's hit-making prowess and impact on 2010s mainstream music, so much so that this collection doesn't even include all of his platinum hits.
