Well, given that 2ne1 has only released 2 mini albums, 1 full album and NO album on 2012, this is pretty understandable! ^_^ Here’s a sneak peak into how YG’s mind works. But of course he says he does music not only for the money.

of-course its gonna be small compared to GD/PSY/BB..its for 2012..2ne1 did not release any albums in 2012 compared to them..
Its upsetting but not surprising at how small 2en1’s sales are compared to BB/GD/PSY. We know its not the girls because they are SUPER WOMEN in talent, beauty, charisma and swag. It seems like they are just not high on the priority list for YG> They have to patiently wait for the music to be handed to them. Thank goodness Dara has her endorsements and she can act if YG allows her too. But what will happen to 2en1? will YG let them slowly dissapear as he spends more time with the new groups? is it a man thing where women arent as important as men in Korea? i dont get it.
2ne1 did not release any albums this year so its expected..lets just wait..this also happened to BB right when 2ne1 debuted..but after that YG gave BB a big comeback and i’m hoping its gonna be the same with 2ne1…
