If you are already an SNSD fan, this song might take a few plays to get you attached, but soon you will find yourself singing it in the shower. It's hook is the predictable "Bring the Boys Out" which isn't as strong or immediately catchy as some of their best songs. But there are some unexpected shifts in the song which keep it fresh for the whole track.
The English version of the lyrics are pretty kitsch. They do maintain a positive and upbeat feeling that has always drawn me to their music. It makes it pretty easy to learn the lyrics when you can more or less guess what they are going to say next. For me, this doesn't take away from the enjoyment of the song, but I can see how some fans might be disappointed that they lyrics have been so "Americanized." I recommend checking out the Korean version of the song which lyrics (from what I've read in translation) are a bit less predictable.
The vocals have been treated quite a bit which personally, I feel these girls don't need. However, this is for a western pop market and that sound is in right now. Combined with the style of the lyrics, it's pretty clear they are going for a pop dance hit with this song. There's not very strong accents in their English that I notice except a bit with Sunny (I can forgive her since she's SO cute in the video ><).
Best part? If you happen to speak English and not Korean or Japanese, this is one Girls Generation song you'll actually know what the words mean while you're singing!
If you have never heard of Girls Generation and you are a pop/dance fan you will probably enjoy shaking your hips to this one.
