Soundcloud is my go-to example of bad UI design that has progressively worsened over the years. This, though, would be a step in the right direction!
Bigger than their UI problems, though, are their UX problems. I don't care what the site looks like as long as I could have three features:
1) no comments from strangers, ever. (they are mostly spam or content-less)
2) no auto-advance when I am viewing the page of a single track. (it often advances to tracks by artists I to whom I don't even subscribe)
3) let me sort every list I can produce. (the current sort of artist pages seems to be an incomplete bogosort)
As someone who's been using SoundCloud for 6 years this has always been one of the features they've done right. Comments aren't obtrusive, they can be made relevant to specific parts of the song, and they are easy to access (or not access). Sure on very popular tracks with thousands of comments you get spam/useless stuff but on less popular tracks comments can be insightful, provide feedback to the artist and provide information useful to the listener.
I'm almost never playing a single track as the parent comment is complaining about. What is happening is because you have not selected any sort of playlist, SoundCloud's autoplay reverts to "Recommended Tracks" aka tracks that it has determined have been similar to the one you're playing (I suspect they are adjusting this algorithm to promote certain artists/tracks, but sometimes it finds legitimately similar music).
To do what you are asking for you could go to an artist's profile and play the tracks on that page, and the autoplay will continue down that list. If the artist has reblogged songs from other artists/profiles it will appear on their page. You can also play through an artist's likes (which might have more tracks they appear in, and other artists to listen to who play their type of music, with more profiles/likes to play through).
In the end my favorite autoplay mode is just using the stream, which compiles all the posts/reblogs from artists I follow into a "newest" sort. If I run out of that I normally find a profile/likes playlist to listen to.
Maybe I'm using it wrong then :) The only time I play anything on SoundCloud is when I follow a link from Facebook or elsewhere to listen to a specific song or mixtape. Anything else playing after that, no matter how relevant, is not what I wanted or expected.
