What makes Outside by Ellie Goulding notable?

'Outside' achieved significant commercial success, peaking at number six on the UK Singles Chart and earning multi-platinum certifications in several countries. The song exemplified the growing trend of pop artists collaborating with EDM producers, solidifying Goulding's position within that evolving market. By the time 'Outside' was released in October 2014, Ellie Goulding was already an established artist with a string of hits, including her breakthrough album 'Lights' (2010) and the critically acclaimed 'Halcyon' (2012). This collaboration with Calvin Harris marks a transition as she explored more mainstream electronic sounds while maintaining her signature emotive style.
