As I've had one of those days when you feel down for not particular reason or for some that come all together... I've decided to post a song that usually makes me happy:

ラブラブなカップル　フリフリでチュー 

by Japanese band Rag Fair. They sing 'doo wah' kind of songs 'a cappella' and are simply amazing. The way the six of them combine their voices to sound like the instruments should, and the great voice the main singer has, made them so nice and easy to listen, at the same time that the melodies and the chorus are quite catchy too.

I discovered them watching Utaban (Smap's Nakai's variety show) and since then I am a total fan of them!

Here is the song but I really recommend you to watch the video that you can get here, because it's very very cute.

The first pic is from Air, the album where you can find the song I recommend. The second pic is from a more recent work, Circle, that I truly recommend as well.
