Who Do You Love was released in February 2019 as a single by American DJ duo The Chainsmokers featuring Australian band 5 Seconds of Summer, and later appeared on the album World War Joy. The collaboration mixed electronic dance production with pop rock vocals and became a chart hit in several countries. Short excerpts circulated online as edits, fan videos and soundboard clips, where the memorable title line became shorthand for relationship drama. Its brevity in this form makes it useful as a recognisable sting rather than a full musical moment.
