DPM App Store?

So my IT guy comes up to me the other day and tells me that he wants to take my unplugged acoustic style into this century.  I'm thinking that I need to fire him because that's not what I do, but he convinces me that we can make this happen, entertain the people, and I will still keep my americana/folk cred.  Well since it will entertain you, the people, I was more than willing to give it a shot.  So my question for YOU is what type of app would you like to see.  Let me know what you think, and we'll pick the best options and I'll put the IT guy to work.  ;-)  See you soon.
