This is all great stuff. But until Spotify fixes some very low hanging fruit problems, such as not playing a song ever again if I click "don't like", I find it hard to believe they will use anything remotely complex as this.
Well yes, but it is "just" an internship, in which you can do something else than the company is doing. I hope they eventually will use this work, after fixing the low hanging fruit.
This was my thought exactly. It seems like they're putting the cart before the horse a bit.
