SISTAR Releases "Shady Girl"

Sistar has just released their second single song "Shady Girl."  The style of the song is

less bubbly than "Push Push," but still has an upbeat feeling.  The part of the chorus where Sistar sings "I need you boy" reminds me of "Push Push" and that's not a problem with me because I'm still listening to "Push Push" xD.  Sistar is just one of the numerous K-pop girl groups that debuted this year.  Will they survive the competition?  I hope there's enough room for all the groups because I'm sure each girl group has a lot of talent.
