What tha Bizness Is??

So I have been on the hunt for my new online hustle. I have ran many businesses before but I always run into one major problem... TIME! I am looking for a company that will damn near run itself. Almost completely outsourced. Basically I am looking for Passive Income. Any suggestions? Being that I am in the music industry I would like for it to be about music but I really don't know. Just in the brainstorming phase right now. I may write a book and do some tours. If you have some help hit me up.

OTPM.
