Neat idea I suppose. But no chance I'll be downloading/paying for demos.
Besides, I'm guessing most of those demos were released on Driving Baby Lips.
Seems like these demos are just for Bubblegum and Bulldozer (like a demo for each song). Driving Baby Lips was really all over the place as far as source albums.
For anyone that's done the subscription for this, are you able to download the demos to your phone/PC? And how do you eventually cancel your yearly subscription?
EDIT: I paid for the yearly subscription. For the love of flying spaghetti monster, stay the hell away from the premium portion of this app for now. It crashes all the time. You can't download the music and it tries to stream from Soundcloud, which doesn't work most of the time. Awesome artist, terrible app.
