At this point adding numbers to the people agreeing seems pointless, but I'm also in this cat3egory.

Sure, I've had some good recommendations, but I'd expect any recommendation engine to do that just by chance.

What I can say is that Spotify has never proposed something truly new and interesting to me. If I listen to a lot of metal, it'll recommend me the most bland stuff in the same genre. What's even worse is that it keeps playing the same songs over and over again. It's like the recommendation engine just gives up and starts repeating its suggestions again.

Your last paragraph is why I got rid of Spotify. I like music to move me. It was amazing how I could start a run of upbeat, pumping, specifically chosen songs and then have the recommendation engine suggest 30 minutes of cruisy blandness..

I simply gave up on it. Why have access to everything when I only got the crap. Going back to my personal collection increased my good/bad song ratio considerably.
