Just finished listening to the Nine Muses mini Sweet Rendezvous (a few pages back I said I'd downloaded their discog and was working my way through it) and I'm slayed. My favorite of their releases that I've heard so far.
In first place was SG Wannabe (debut year 2004) with a total of 24 hit songs, including three collaborations they did with Kim Jong Kook, Brown Eyed Girls, and KCM. In second place was Big Bang (2006) for a total of 22 songs all on their own, meaning no collaborative works! For reference, sub-unit GD & T.O.P had two hit songs "High High" and "Oh Yeah."
In third place was female power duo Davichi (2008) with 18 hit songs! After these two talented ladies was another YG group 2NE1 (2009), which came in fourth place with a total of 16 hit songs. Unsurprisingly, the debut years do appear to be important factors in this list--at least for the top four.
In fifth place with a total of 15 hit songs were five artists and featured both older and newer artists: MC Mong, Busker Busker, Lee Seung Gi, Brown Eyed Girls, and SeeYa. MC Mong had hit songs like "I Love U Oh Thank U," but he did not release a new song since 2011, the same year SeeYa disbanded. On the other hand, Busker Busker began in 2011 with 'Super Star K' and officially debuted in 2012 to release quite a number of hit songs over a very short period of time. Lee Seung Gi debuted the same year as SG Wannabe (2004).
Any SG Wannabe stans? and Damn YG family slay a little.
