Founded by Brendan Mulligan, the man behind ArtistData, OneSheet is essentially an aggregate of any and all social networks into one simplified site. Setup, for the most part, is as simple as typing in your usernames to link your accounts together, and once that's complete, you'll be able to adjust the position of each widget, music player and social-connectivity button. The whole process takes around five minutes to complete -- provided you actually remember all of your various usernames.
The point, according to Mulligan, is to offer an easy-to-update landing page. Nothing more, nothing less. As one social network or music service dies off and a band moves things around, there's no need to create a whole new following; you can simply add the new details into Onesheet. If nothing else, it should eventually become the first result on Google, then fans can decide from their which social network to follow you on.
Most importantly, it's simple and clean. Thank goodness the bloated days of MySpace are long gone, because the look of Onesheet's better pages is fantastic. A simple music player, links to social networks, and that's it. There's also room to add show details, sales details and plenty more. Essentially, it is a fully functioning, easy to set up, free website for bands to connect to everyone at once.
Of course, an effort to monetize the whole thing is in the works in the form of extended customization and third-party linking. The system is stripped down (which also happens to be part of its appeal), but in the future, more added features will cost a little money. For now, it seems like a viable means to replace traditional band websites (and the cost of hosting them) with a clean landing page. It's still in beta, but you can sign up and setup your page about as quickly as you can type.
