I'm all for helping musicians get the word out about their new websites. However, you are going about it the wrong way. You may not be an automated poster trying to sell cheap watches, but this is still spam.
In fact, from your "recruitment" video, it looks like it's going to be subscription-based. If that's the case, then this is absolutely nothing more than spam. Good luck with your new venture, but if you want it to take off at all you're going to need to change the way you promote it.
