Just the other day Grimes reminded us on her blog that she wrote a new song with Fun.’s Jack Antonoff for HBO’s Girls, and that the episode she wrote it for is premiering tonight. Well, looks like we won’t have until tonight to hear the track, as the track has been uploaded to Antonoff’s Bleachers Vevo account. Sounding somewhat like a Grimes singing atop a Fun. track, the sparkling “Entropy” is just further proof of Grimes’ impressive versatility. This isn’t the first time the two have worked together, as they collaborated last year on the powerful “Take Me Away.”
