I utilize Twitter, Facebook and my Blog to promote your music. @WeberMusicBlog on Twitter has some 14,500 followers. Facebook.com/WeberMusicBlog has 2,300 "likes." Then, there's MarkWeberMusicBlog.com, where I can post detailed articles about you/your music, including a nice graphic, a soundcloud or YouTube embed, link(s) to your site(s), and, best of all, details about who you are and why someone should care to listen! The post stays up indefinitely.
I've been writing about music makers professionally since 1998. It's what I love to do.
Yes, I have an eclectic taste, so I like to promote all sorts of genres. As long as it's "family-friendly" and not explicit, my audience can handle it.
