The 20 Best K-Pop Songs of 2014 - 3. G-Dragon & Taeyang - "Good Boy". G-Dragon and Taeyang's collaborative effort, a trap-inflected banger with heavy bass and pulsating synths, is 2014's most addictive single and guaranteed to be a new club anthem. The song structure is familiar and accessible, but the BIGBANG boys blur the line of rapping and singing as the guys trade off lines. GD x Taeyang hardly feels like a collaboration, but more like a cohesive artist.
