It's not just slotMusic trying to sell digital music in some sort of physical form -- this so-called Playbutton concept has been making the rounds for the past few months, and it's now finally set to go on sale in February with eight different albums to choose from. As you might be able to surmise, the button is actually an MP3 player, but there's no way to get the music off of it and, to keep things as album-like as possible, there's no shuffle button either. There is a bit of room for some artwork to let folks know what you're listening to though, and you can thankfully plug in your own set of headphones. As for how much they'll cost, Playbutton founder Nick Dangerfield says albums sold on the buttons could be as much as $30 apiece, although he notes that it'll be up to the artists to decide how much they want to charge -- he suggests the "ideal price" would be $15 if bands sold them at shows.
