It's kind of hard to translate what the title is supposed to be because it's written in katakana. It sounds like it's supposed to sound like "Sleepy Heart/Chest", but I can't be positive, so I'm leaving the title in Japanese. There's also a lot of sfx sounds in this song and your guess is about as good as mine as to what they're supposed to mean. I tried. lol
