Teen top covered "She's my girl", an Indonesian song. It's from S4 and Hyuna from 4minute rapped for their first song.

They also sang the song in english

I think the song was originally in Korean (I guess). They've been in South Korea for six months to train their vocals, dance etc.

I just found the video of Teen Top singing to this song! This is really something! They even sang it in Indonesian

And, S4 made a cover of 2AM's song :D and Teen Top's song

I think it's very remarkable that the Asian-Pop music is such a big influence. It got more and more popular that I almost forgot how the old music was before this kind of style (catchy music and the members dancing) came - especially thanks to K-Pop. I'm wondering if this will be the style Asia will have in the future, because I hope there will still be other genre of music on the charts.

Anyway, I was really amazed by S4. Good luck to you guys! Thank you for showing others that there is indeed a country called Indonesia. There are still a lot of people who knows and was in Bali, but don't know where Indonesia is -.-;;
