Well, I only recently listened to 'Ma Boy'. Honestly, the MV reminds me of the Pussy Cat Dolls
I keep watching it over and over again though for Hyorin's awesome "S-I-S-T-T-T-A-R!" in the intro, her amazing vocals, Bora in bed, Bora looking like Lee Hyori in that purple tanktop, and that finger twirling part
I like the looks in 'So Cool'
Might have to give the song some time though. I expected a bit more from SISTAR, but then again, it's not like it's them who writes and chooses the songs, so I'll live. The moves are far from cool, I must say. They had sweating under the collar
I personally think that Sistar is one of the hottest groups out. I wasn't really feeling Dasom when they first came out, but damn that girl's a cutey. Really loving her new hairstyle; it reminded me of Eunjung when she was getting ready to run that race.
