without using a translator.. I think the title to the first one is koi wa moutakusan, or something like "love is too much" or "too much love"? Anyways I'm vibing to The Dynamites to start off today, some japanese groups took western music and then just put those rhythms to japanese words! It's not quite the masterful work Happy End did but I can still vibe and bop my head to it, it's good fun music.
second one should be easily recognizable to a lot of people, it's a really fun cover!
