I just spent 50 bucks for a yearly subscription to one of your competitors a week ago. My biggest complaint about them is that I can't get a list of tracks that I've really enjoyed and there's no upvote, play more like this feature. I don't care about social "likes" but some songs in an otherwise great playlist are just really grating and throw me right out of the focus window. It would be nice to say "don't play this again"
