As reported by Mixmag, Soundcloud struck a deal with Merlin, a group that reps 20,000 independent labels including Armin Van Buuren's Armada. This will allow them to start putting ads on tracks and collect revenues.
In a way this is great news even though fans might have to slog through ads from time to time. But when you take the view of rooting for Soundcloud to succeed long term, this is one step to help them accomplish that goal. I'm all for that as this electronic dance music movement wouldn't be nearly as strong if Soundcloud wasn't around.
