There's a recurring issue with SoundCloud where tracks disappear from your playlists. This can be due to a multitude of reasons, i.e. the uploader deleted the track, made it private or copyright infringement.
This in itself is not a huge issue, and cannot be solved anyway, it must function like that.
But! SoundCloud removes the track completely from your playlist without informing you in any way. Meaning you have no idea what tracks are disappearing, and thefore you have no possibility of looking for them again.
Spotify has an option called "Show unavailable songs in playlists" which will show you "ghost" tracks containing the metadata needed to identify the track, but not the audio data to listen to it. That's exactly what is needed for SoundCloud.
I'm putting a lot of effort into finding music here and building my library. These occurrences where I realize a track I really liked is missing are horrible. Many times I can't remember the artist or track name, and spend a lot of time searching in the dark for it, never to find it. It's the worst feeling.
What's worse is, for every time I've realized a track was gone, there are probably 10 tracks missing that I never even realized. That's not ok! This ruins the integrity of your playlists and forces me to use other means of collecting music. Fix this please.
