Clearly, you should be in real estate immediately. It's obviously super easy, and with your math that's super accurate and in no way an understanding far separate from reality, clearly you'll be a multi-millionaire within a few short months.
Good luck!
If I can, I buy direct downloads.
If I can't do that, I'll buy the CD (as long as its direct or a small label).
If I can't, or its one of the big labels, I'll find it elsewhere. I'd rather buy merch to support the artist directly than buy anything that goes through the big labels.
