i'm not really into music, at all, but would easily pay $50/month to be able to have this functionality, too. even just the tools being what they are i've spent over a dozen hours playing around with it because it's so much fun. add the ability to separate parts of the tracks and select portions specifically to change and i'd use this constantly, all the time
