Can someone give me some suggestions on how to increase sales for my music?

A great idea might be a "virtual" tour; you could do a live tele-conference call with your fans where you sing a song or two, tell them about what you're working on, and answer questions from your live callers. This gives your fans a way to connect with you IN PERSON and actually feel like they "know" you. It's a step up from the social media marketing you're currently doing (which is right on the money by the way). In fact, promoting your virtual tour on Facebook and Twitter will allow your fans to share that information with their friends....setting up a great opportunity for the "tour" info to go out viral. You could also offer a free download of one of your songs to a lucky listener by giving them a website address at the end of your call where they can enter to win. This gives you a way to build your mailing list which is HUGELY important for future promotion and sales.

So, you could do a whole series of virtual tours throughout the year in this same manner and exponentially build your fan base and following with very little time, effort or overhead.
