As a new user just discovering this website, I need following information: - What does DropTunes do? Not everyone understands what "Your Music" + "Dropbox" means. Actually, most normal people don't know Dropbox at all. - Are there also mobiles apps? Can I use that on my phone? My iPad? If I don't know I don't want to try it. - Where should I put my music on Dropbox? Why does it needs my credentials? Could as well use my public folder.
