Well... Facebook and Twitter are a good start. Creating a Facebook page for your business and start asking friends to Like it. Good for your site ranking as well. Are you promoting an album? I've noticed that there's a lot of sites in your list that's geared towards musicians and music in general.
Did you forget youtube? Youtube is the best way to promote videos, Do youtube optimization and optimize your videos and bring them on the first page in google
All social media websites are good for business, but it depend on your activities if you are updating your social media page on daily bases, then you can get flood of traffic, but it depend on you that how many social media website can be managed by you in once time. I am using around 4 to 5 social media website but I like and most useful for my business, "Twitter" is good for me. I generate around 70% revenue from Twitter.
You are absolutely right, I think. It depends on the way you want to promote your products/services and what they are.
