Thanks for posting these videos!! There is always more than one way to skin a cat. I agree with seo strategies outlined in the videos it just depends on the market your are targeting and how you plan to engage them. I would only add that you should do more market research as is pertains to your music. Before attempting to go after a market you should find out what it is they like then give it to them. There are tons of ways to do market research but ultimately it comes down to picking a niche and finding a way to reach them fast, and at an affordable price. SEO is great but it is really slow and with the competition only growing everyday it is becoming harder and harder to care out a niche using SEO. It is alot of work to do SEO only to find out that the market is not buying.
This is why testing the market before you go long is so important. I would recommend running paid ads and sponsored ads to people who are already buying before attempting SEO to gain traffic to your site.
