Spotify told Variety that the chances of acceptance will depend on accuracy checks. Line-In both supplies a number of musical aptitude surveys and verifies whether or not other listeners are making similar suggestions. If you can't tell the difference between Run the Jewels and Run-DMC, you probably won't make your changes stick unless many others are saying the same thing.

This is the first large streaming service to open the doors to user edits, but it might not be the last. Spotify and its rivals depend on discovery to reel you in -- you're more likely to stay subscribed if you can find an obscure album or listen to a playlist that caters to your exact tastes. Music is defined by fuzzy categories and other human imperfections, and crowdsourced edits help acknowledge that reality.
