What did you do yesterday? Well, the boys of Block B want to know! Block B released a music video for their new song “Yesterday” and I have to say these boys really caught my attention. This song is really catchy, I catch myself singing it throughout the day, I just love it! It’s a song that can bring up your mood or jam to when you wake up wanting to start off your day singing and dancing. This song is great, you won’t regret listening to it.
