The new track's called "Trash" and it can only be heard via a special hotline.

If you call the number, you'll be welcomed to the "caged pillow feelings network" and be given a set of options. Press one to hear "Trash". Press two to hear a radio broadcast/the US national anthem. Press three to leave a message. If you choose the fourth option, you'll be greeted by a woman's voice who'll help you "to touch the world of caged pillows... you just have to look in the right light... we will guide you through the process step by step over the next few days." Apparently there'll be updates on Instagram in the coming days. "The feelings network is a living breathing object and changes day to day, so you might want to save this number to your contacts."
