2NE1 ranked the ‘Lollipop’ no.1 on the Korean online chart without any promotional TV appearance, and then their official debut single ‘Fire’ also ranked no.1 on the chart, and won lots of awards as well. The record 2NE1 have made for last couple of month was very sensational for rookie. The new single of the album ‘ I don’t care’ is produced by the main producer of YG, Teddy who produced ‘Lollipop’, and ‘Fire’, and Kush the member of reggae group Stony Skunk. ‘ I don’t care’ is kind of medium tempo with reggae style R&B pop compare to other songs with fast beat and strong hip-hop sound. People thinks fast dance beat songs are good to listen to during summer time, but normally countries with hot weather listen to slow beat songs like reggae. The catchy reggae beat of 2NE1’s ‘ I don’t care’ will cool down this summer.
