Mixcloud founder here, thanks for the vote of confidence. One key difference is we internally measure success or engagement in terms of minutes listened not play counts, and actively optimise for this. So often the visible play metrics don't actually respresent true human engagement. It's something we're thinking about a lot internally right now, and we might start exposing it shortly. I suspect most people will be very surprised for the better when we do.
Don’t get me wrong - I agree that minutes played is a much better metric than play count - in fact I always wondered why Soundcloud wouldn‘t go a few steps further and not only show minutes listened, but also where those minutes were spent within your mix, like a heatmap over your upload‘s waveform to see which sections were most popular or where listeners stopped listening.
However, regardless of the fact that you use different metrics, for me it feels much harder to find an audience at Mixcloud. It‘s not that I‘m very popular at Soundcloud, but the small circle of like-minded followers I found there doesn‘t seem to translate very well to Mixcloud. Again, that may change with Soundcloud‘s demise.
That is the same internal goal that SoundCloud has. Play counts is just what users want to see. All of SoundCloud's internal optimization is around listening time.
