Girls' Generation has made a drastic change.

They recently made a comeback with a tough hip-hop sound, which is very different from their usual feminine and cute concept. Yesterday, they released their "I Got a Boy" music video, which showed many different styles of dance and song.

This 5 minute video showed the group's 180 degree change. They wore sneakers instead of high heels and flashy outfits rather than pastel tone girly outfits. They showed off 'B-Girl' dance moves as well.

With groups such as Girls' Generation and 2NE1, each group has their own distinct style. However, with this new concept, it seems as if the girls have branched out of their comfort zone to try something new.

Their new image contains a fusion of hip-hop, electronic, urban, retro and more. The song even shows parts of what seems like a musical in the middle of the music video.

The video received over 10,000 comments on the day of its release. It is rare to see this many comments on one video, however, due to their surprising change, many fans were shocked.

Many producers and other celebrities have praised their new style and like their new concept.

Their new song also ranked number 1 on many real time charts online.
