We just love it ,whenever our favorite kpop idols decides to do a retro theme for thier upcoming  back .Because  it brings a new side of them that we are seeing and that we the fans love.

Here are some of your favorite idol that do retro theme concepts.

Twice -Signal

Now not many fans  are fans of this 2017 Summer song , but I actually  like the song and beat of it actually. Everything about the video is fun and colorful including  the outfits .

Mamamoo -Mr Ambiguous 

This is actually  one of my favorite debut of all time ,well there's  Girls generation  ITNW but this song comes in second. This song is pretty  good song to jam to and the vocals are off the chart .

Secret -Shy boy 

I find Secret did a good job with song , the video  wnd outfits  were colorful and bright which I like about  it.

I  just wished the storyline was stronger because it seems like it emphasize more on disliking bad boys rather than chasing for shy boy. I want a shy boy to be the main character. The dresses in this video is pretty and lively so this concept is really great for this song.

Ladies Code -So wonderful 

The chorus is a bit repetitive, but overall if you can get past that, it’s a pretty nice song to listen to.The singing is nice and the song has a refreshing feel to it (that’s the best way I can describe it).The girls of Ladies Code tell the story of a man who doesn’t see them as anything more than a doll for him to dress up.

My only complaint is that I wish we could have seen more of the girls’ emotions, especially in the end.

Spica -You don't  love me

From the concept, to the outfits and song message  was perfect.

I just wish they would more recognoztion for this song .

and they really go out all the way to make this song , I just love this part, I find it cute and sexy at the same time.

Snsd -Lion heart

Ahh the Queen of retro concepts , once you  see Girls generation  do a retro concept you  know the song is gonna be hit. Although this is not the first time Girls Generation did a retro theme concept ,but back in 2010

they dropped "Hoot" for their  third mini album comeback, where they portray as sexy Spy agents, featuring  label mate Siwon from Super Junior  .And I instantly fell in love with this comeback, the dance moves are catchy of course Girls generation never disappointed, Four years later they returned  with another retro theme  comeback  "Lion heart" Another hit song again Snsd never fails when it comes to doing Retro concepts. 

Wonder girls-Nobody

One word Iconic 😏😊😊😊😊the song that introduces everyone  to the kpop scene ,the song that captures  out heart .From the one and only Wonder girls .

Tara 

How can I forget this hit classical song,  I really the beat of the song it very catchy and one of my favorite T-ara songs up to this day.
