Have you read the analyst report this week? It was in yesterday's PR. It covers all of PMCM's past & current ventures including the music, & recommends it as a long term investment.
In any business many revenue streams is advantages. Let's say the MMJ stalls for a bit, (hopefully not) but revenues can still be realized on another front, that's good business, just like I do not own one stock & one sector in my portfolio.
