QT is the duo of Sophie and PC Music's A.G. Cook, and we've been hearing snippets and live versions of their debut single "Hey QT" for a few days now. Now they've shared the complete track, and it's a great, bubbly, catchy number in the vein of our favorite jams from these guys' solo projects - not to mention, we want to meet the girl who keeps doing chipmunk-style vocals for these Sophie tracks. Check it out - a physical single is coming soon via XL, and we'll keep you posted.
