Mayday's new album "God's Children Dancing" has a song called "Garbage Truck", and Mayday also has their "Garbage Truck", which is responsible for "pretending" members' dissatisfaction.
In the song "Garbage Truck", a lover or friend is compared to a "garbage truck" and is willing to let go of the troubles of the loved one. There are garbage trucks in May, and absorbing "garbage" is the best blessing.
