Apparently they've had similar issues on Mixcloud:

And even if hip hop/trap/neo-soul/etc aren't your style, if you're into any electronic music at all there's probably something for you on Rinse.fm (unfortunately they're more an internet radio station than a platform like Soundcloud, not exactly apples to apples from a user perspective).
