I see absolutely no reason why the SoundCloud team cannot add the "Next Up" (or "queue") feature to iOS. It exists on Mac and Android for a reason: it's a feature that's nearly universal across music streaming platforms, it's immensely helpful, and there's no justification for its absence from iOS other than deliberate laziness. The app is so sleek and well-polished otherwise (they even added updates just the other day to the appearance of profiles on the iOS app). A mobile queue would be so easy to implement and requires very simple programming skills. They could add and debug the feature in a single day's work. So many people I know have switched to Spotify for this one reason.
How might we go about convincing the team to make this change? My impression from reading past posts is that these queries rarely get read or even considered. Is there any way to contact SoundCloud directly? Adding this feature seems like a no-brainer to me.
