I found SoundCloud great about 5 or 6 years ago - engagement was high, and I was getting lots of comments and interaction on my music, but lately, it has nosedived. Not sure if because there is just a lot more noise (pun intended) on there nowadays, or other artists have simply abandoned the platform??
BTW - my handle is: https://soundcloud.com/cyberferret
(very close to the adjective-animal name thing that another commenter mentioned! :) )
Look at the organic engagement from the tracks I posted 5+ years ago, versus later ones and you can spot the down trend quite easily!
