DI.fm - was my favorite for many years. But it's Flash only that crashes often and extremely annoying ads. Spotify - ads and the discovery is broken. I usually listen to mixes and Spotify is more for albums/artists.

I'm curious—is the music you were listening to on SC not available on Spotify, or not in the same amounts? Obviously there is a lot of new, original stuff on SC that's often not 'officially' released or distributed. But it would seem that, nonetheless, that's still not enough of a draw to build (enough of) a subscription service around it?

Disagree.

Discovery and 'play related' are totally broken on Soundcloud compared to Spotify.

On SC, you can follow hundreds of users and get inspiration from them but for me this never worked or matched my taste in a consistent manner.

So either you listen always to the same tracks the eight hours or listen to some unrelated tracks or must fiddle around with SC's also broken UI.

If you've got Spotify try JQBX: https://www.jqbx.fm basically a tt.fm clone. Great for passive listening.

DI (digitally imported) does a pretty good job of filling my work-electronic-music fix.

I agree. my collection of liked mixes on soundcloud is the perfect soundtrack for getting work done. I prefer to listen a song I like, specially electronic, in a dj mix than in a playlist.

Depending on your music preferences YT does a pretty good job at it, there are many more gems hidden on YT compared to all the other music services combined.

Spotify?

Edit: Tons of playlists. No vocals.
