There's no way these are just demos. They're really good. Well produced, catchy, quite innovative. The vocals aren't that great, but she's never been the greatest vocalist and it's not uncommon for voices to deteriorate a bit as people age. Same thing happened to Whitney and Mariah. Vocally, she sounds similar to MDNA. But song-wise they're waaayyyyyyy better. Like a billion times better. MDNA was terrible though. 'Birthday Song' in particular
This slays though. I use.
