Thanks, we try to talk to users as much as possible.
What you're referring to is the autoplay of related tracks. Great feature for background listening - not so much for your use case :)
You can turn it off by going to the options screen. Go to the "person" icon tab, then the 3 dots button on the top right. De-select "Autoplay related tracks".
Any other feedback and I'd love to hear it. You can always DM me on Twitter @colemercer as well, I keep it open.
I'm a PM at SoundCloud and want to let everyone know that this post is very, very old. I believe over 2 years. Difficult to tell from the site though.
That said, the feedback here in this thread is good feedback, so I do appreciate everyone taking the time to write it. Much of will be resolved soon, so keep on the lookout for future updates.
Let me know if you have any specific questions or input.
